Making a DVD with opensource

Hello, Someone asked about creating a DVD using Linux. I'm not going to be at the next MUUG (going to Chicago) but I thought I would share this URL that I've recently tried and found works very well: http://www.wlug.org/files/howto_dvd_talk/HOWTO_MAKE_DVD -Montana Quiring

Further to the discussion of free/vmstat and monitoring memory, I dug up some old articles that explain how to interpret the output of some tools.

Burning a DVD
by Mike Pfaiffer 09 Nov '05

09 Nov '05

Tonight at the meeting I was asked to post what I did to get a video DVD burned. I'm more than happy to do so. I'm tickled pink I got it to work so it's a pleasure. This is the simplest case where a single video file plays automatically on a console unit. There are separate steps one needs to go through to burn a video DVD. First is to get the video file into an appropriate format. Next is to take the resulting file and place it properly into a directory structure expected by the player. The final part is from the URL Montana Quiring posted earlier. Namely burning the directories to the DVD. This is where I was having trouble before. The tools needed are mplayer (specifically mencoder), videotrans (has a bunch of dependencies including mencoder), dvdauthor (also has some dependencies), and growisofs. I understand transcode can substitute for mencoder and videotrans. Here is what I did from the commandline to get it to work. ============ # part of videotrans - Translate to vob file movie-to-dvd -m ntsc -M 'sample01.avi' # part of dvdauthor - Create the file structure dvdauthor -o DVD 'sample01.vob' dvdauthor -T -o DVD # part of growisofs - Put the directory structure on a DVD growisofs -Z /dev/hdb -dvd-video DVD =================== NOTES: -DVD is an empty directory where the directory structure is created. -/dev/hdb is my burner (found from the KDE hardware browser). -I did not have to be root to do this. There are other things I could do such as lowering the quality or size. Eventually I could create menus. The man pages say subtitles aren't supported yet. I would presume multiple language streams aren't either. I'm not sure if I missed the "-Z" parameter or I used something like "/mnt/cdrom" (in hindsight, this would have been really dumb) last month. Whatever it was, this last line solved my problem. Later Mike P.S. Good meeting. I understood the principals of what he was talking about even if I missed the specific references. -- +----------------------------------------------------------------------+ |Call-A.P.P.L.E. and the Digital Civilization http://www.callapple.org | | http://members.shaw.ca/pfaiffer = Mike Pfaiffer (B.A., B.Sc.) | +----------------------------------------------------------------------+ ----- BEGIN GEEK CODE BLOCK ----- Version: 3.12 GCS/G/IT/PA/SS d s+:- a?

MUUG Meeting, Nov 8, 7:30pm -- Linux Clustering
by gedetil＠cs.umanitoba.ca 01 Nov '05

01 Nov '05

[Posted to man.unix.general and other news groups] ------ Forwarded Article <dk8aa3$hvc$1(a)canopus.cc.umanitoba.ca> ------ From gedetil(a)cs.umanitoba.ca (Gilbert E. Detillieux) The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting on Tuesday, November 8. The meeting topic for this month is as follows: Linux Clustering Mark Spencer, of Red Hat Canada, will be presenting on the topic of clustering. A brief discussion of the different kinds of clusters, as well as the reasons for implementing clusters will be shown. Come prepared to be a participant, as Mark likes to engage the audience in a more seminar style of presentation. The group holds its general meetings at 7:30pm on the second Tuesday of every month from September to June. (There are no meetings in July and August.) Meetings are open to the general public; you don't have to be a MUUG member to attend. ********************************************************************** Please note our meeting location: The IBM offices, at 400 Ellice Ave. (between Edmonton and Kennedy). When you arrive, you will have to sign in at the reception desk, and then wait for someone to take you (in groups) to the meeting room. Please try to arrive by about 7:15pm, so the meeting can start promptly at 7:30pm. Don't be late, or you may not get in. (But don't come too early either, since security may not be there to let you in before 7:15 or so.) Limited parking is available for free on the street, or in a lot across Ellice from IBM, for $1.00 for the evening. Indoor parking is also available nearby, at Portage Place, for $2.00 for the evening. ********************************************************************** For more information about MUUG, and its monthly meetings, check out their Web server: http://www.muug.mb.ca/ Also note that MUUG maintains two mailing lists, called "muug-announce" and "roundtable". If you're not already on these lists, we encourage you to subscribe now: http://www.muug.mb.ca/mailman/listinfo/ The "muug-announce" list is used for monthly meeting announcements (such as this one) as well as other important announcements of interest to MUUG members. The "rountable" list is meant to be a forum for follow-ups to topics discussed at the meetings, or for round-table-style discussion on other topics that come up between meetings. Of course, for this to be effective, we need to reach a certain critical mass. So, please subscribe, and stay involved! -- Gilbert E.

Re: [RndTbl] wintv PVR 150 cards $99 at futureshop this week
by Kevin McGregor 25 Oct '05

25 Oct '05

If you'd like two tuners, check out www.ncix.com for the PVR-500 (now works with MythTV) for $175: http://www.ncix.com/products/index.php?sku=F25260&vpn=1081&manufacture=HAUP… Content-Type: multipart/alternative; boundary="------------010302010500050704060308" --------------010302010500050704060308 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit While it's still on topic, a quick run-down of the Hauppage cards for those unfamiliar with them: PVR-150 : a basic framegrabber. Requires more CPU cycles to do the MPEG encoding work. Works fine if you have CPU bandwidth to spare. PVR-250 : hardware MPEG encoder. Doesn't require much CPU while recording. (However, it takes *more* CPU time to transcode if you don't happen to like their choice of encoding format!) PVR-350 : hardware MPEG encoder *and* hardware MPEG decoder. Doesn't require much CPU time to record OR play back. Playback can be through the TV-OUT port on the PVR-350. Linux supports using the PVR-350 as a display device for X, but only as an unaccelerated framebuffer. In other words, it's really good for playing back MPEG video (in the same format as it recorded it in the first place) but really, really, REALLY bad for doing anything else like playing XMAME games or really, anything other than MPEG playback. On the other hand, the TV-out generates "perfect" resolution for your TV set, and you can theoretically run a MythTV box without a VGA card at all... The key point I wanted to make, is that although conventional wisdom says the PVR-150 requires the most CPU horsepower, that's not always the case. With the PVR-150 you can control what encoding format gets used - and you only have to encode once. With a PVR-250, if Hauppage's MPEG4 flavor isn't to your liking, the CPU has to *decode* and then *re-encode* the video in realtime - actually taking more CPU time than if you didn't have the hardware acceleration in the first place. The other point is that with the PVR-350, you'll get (reportedly) fantastic output quality but that for doing anything OTHER than watching MPEG4 playback, the performance will actually suck - and take lots of CPU time. -Adam Thompson Sean A.

burning DVD on OS/X Panther
by millward 19 Oct '05

19 Oct '05

First, I'd like to thank Shawn Wallbridge for the .PDF files. Great stuff. My question is for OS/X users. I won a Knoppix DVD door prize but since I don't have a DVD burner, I took it to my friend who has a PowerPC OS/X Panther system. To my surprise, his system failed to read the Knoppix DVD, so could not burn a copy of it. We think OS/X can't deal with the Linux file system, probably ext3. How do you get OS/X to recognize the ext3 file system and be able to read from it? Of course my assumption that a Knoppix DVD uses ext3 might be completely wrong. In that case, what file system are we dealing with and, again, how do I get OS/X to read it? I'm not too keen on buying a DVD burner myself since next year Blue-Ray and HD DVD will have arrived and made it instantly obsolete. I once had a programming instructor who refused to purchase his own computer for this very reason. I used to think he was nuts. Now I'm not so sure.

WRT54G, DNS, and DHCP
by Glen Ditchfield 13 Oct '05

13 Oct '05

I have a WRT54G with Linksys firmware (v4.20.7). It's set up as a DHCP server, and when I ask it to show me the DHCP client table, all of my computers' names are there. However, the computer names don't show up in DNS: 'slate' is listed in the DHCP client table, but 'ping slate' doesn't work. I thought I had seen web pages that said that the Linksys firmware could connect DHCP and DNS so that 'ping slate' would work, but I can't find anything now. I do find lots of pages about OpenWRT and dnsmasq... Have I been misremembering things? Is dnsmasq the way to go?
