xDvd on a CD-R???

[aamir12345678]

I've encoded my high quality Divx (20 min) onto a XSVCD with 640x480 @ 5000 kb/s. The audio starts skipping when played in my player. I found out that my Dvd Player supports at max 5700 kb/s XSVCD. I use TMPGEnc to do a 2-pass VBR, and I put the upper limit as 8000 or 9000, so at higher motion scenes, the audio starts skipping, although the video stays stable throughout. I need to give my file a Dvd header, but I do not want to change my resolution or bitrate or framerate (23.976 fps). How can I author & burn such Dvd? Please tell me its possible.

I'm not sure I understand completely. I have read this before. I haven't tried it yet, but is the Dvd Patcher (the program you use to change the header) actually going to reencode or resize the 480x480 resolution to 352x480 to make it fit Dvd specs, or is that just for the "header". Either way, let me give it a shot.

I tried it. The result was disgusting. I took at my player's miniDVD compatability. It should be able to play it, but this file looked bad even on my pc. I authored it with DVDAuthorGui, created the .iso with ImgToolClassic, and burned it with DVDDecrypter. The results were horrible. I took a look at the video output that TMPGEnc gave, it was crisp clear, but when I tried to author & burn, it messed up. What am I doing wrong? Do I need different programs?

I once made a miniDVD using Ulead's Video Studio (trial ware). You load the video files, select Create Disc-->DVD. Insert a CD-R, and burn.

DVDPatcher just changes the header, not the actual resolution. I don't see how this would help you.

The problem with max bitrates on a CD is that the data on CD is less densely packed, requiring a higher spin rate which many DVD players cannot achieve.

Very few players will correctly handle cDVD or mini-DVD, which is DVD-format files on a CD.

The seemingly obvious answer is to lower your maximum bitrate to a level your player can handle.

Is your CD file resolution 480x480 or 640x480? Neither is standard for DVD, though I doubt this is your problem.

The notion that my player can handle miniDvd I got from this site's DVD Players compatability list. It also shows that it can handle a max of 5100 kb/s for XVCD and a max of 5700 kb/s for XSVCD. The mpeg2 that I'm making is done with 2-pass VBR with a min of 2000, avg of 5000, & max of 8000. That's why I need my DVD Player to recognize my mpeg2 as a DVD, and not a XSVCD. If I lower the max bitrate to XSVCD's upper at 5700 kb/s, I might as well go with a CBR of 5000 something kb/s. My VBR does me no good. Also, I need this to be an xDvd because I do not want to up my resolution from 640x480 to full D1 720x480. The video, as I stated before, plays smoothly. It's the audio that skips at higher motion scenes. I used DVD Patcher to change the header to fool DVDAuthorGui that I had a DVD compliant m2v. After it authored, I used ImgTool Classic to create the .iso, and DVDDecrypter to burn it. It burned and the player recognized it as a DVD, but you cant hear anything, the video is choppy, there is one video where you can see, and another is starting to the right (almost dual-pane), and there is this big ugly pink box that covers more than the bottom half of the screen. Something went wrong, but I don't know what. I did choose Center Custom Size for the Video Arrange Method for TMPGEnc to get "widescreen." I've tested this before, and it gives the "widescreen" look. Is there anything I can do to get what I want? Oh, also, I chose mpeg2 stream (svcd) for my video stream for TMPGEnc. Is this where I messed up? Should I have done mpeg2 program vbr for the stream?

OK - if you're gonna make a mini-DVD, then choose the DVD MPEG types, not SVCD. I personally would minimize any non-standard options until you get something that works, then start customizing. You're trying to get a non-standard screen size to work on a non-standard media, you've got enough problems.

Did you try changing the audio to AC-3? Try making a cDVD with a 720x480 file and see if that works.

I had similar problems with mini-DVD on my APEX, I found that a 720x480 XSVCD with hi-bitrate and MPEG audio worked well and gave me an extra 100 MB storage, to boot. It was also more tolerant of different video sizes, namely 480x480.

I think your final answer will be to do a VBR with a MAX of 5700 - possibly slightly lower or higher - and an average more like 5000 or so.

SFAIK, going to cDVD does not get you any better tolerance for hi bitrates or different video sizes than does XSVCD, in fact these may be worse.

[aamir12345678]

You are right. Bitrate tolerance has only to do with the media, and not with the header of the file. I finally authored it and the dvd player recognized my cd as miniDvd, but the same audio skipping happened. That really sucks. I might have to buy a dvd burner to get the quality files I want. The part that sucks is that I just bought these CD-r's. I'm kind of angy right now. Thanks anyway for the help though, but just for the point of information, you can make an xminiDvd. The video still played crisp clear.
