SVCD Some DVD Players OK, some out of sync... Computer is OK

[khaltire]

I noticed that some of my perfectly authored SVCDs lag on some DVD players (the audio)... Although, I did also notice that others do not lag, mostly the higher end ones? Does anyone know what could cause this? Perhaps they have features that I can look for if I want to buy a DVD player? So here is my question more clearly:

For a standalone DVD player that plays SVCDs with the audio/video in sync, is there a certain feature I have to look for (say "Dual Laser Pick-up" or "Progressive Scan" or whatever)?

The other day at Costco, I tried 6 DVD Players, where 3 of them played the audio in sync (usually the ones over $100), the others being rather cheap ones (mostly no name brands). I am using DVD2SVCD and TMPGEnc. All help is appreciated -- thanks!

khaltire: Do you downsample the audio from 48 to 44.1? Many dvd players will not play back the audio in sync if it is not down sampled i.e. many of the Sony dvd players are like this. I use the header trick and downsample all of my svcd's so they will play in a variety of dvd players. Will

Yes, I do downsample so that I can create a standard compliant SVCD (more supported). Sony's barely play anything besides VCD, I have one my self. Still, I am unsure of the reason that SVCD's only play in high end machines... There must be an explaination, considering SVCDs are MEANT to have 44.1kHz am I correct?

khaltire: Well I am afraid I am at a loss. Couple of things you could try are making sure the aspi drivers from the dvd2svcd website are installed. Also under the bbmpeg tab you could change the movie offset to 0, but I doubt this will help. Lastly try doing the header trick. It will make it play in a lot more dvd players and possibly some of the dvd players you have tried are US versions that need the header trick to play svcd correctly. For example many dvd players shipped to the states are designed to play svcd's, but in their firmware/bios. their set not to for US versions. I.E. The Sony's are like this. But they can and do play svcd's using the header trick. Or under bbmeg in Advanced settings you could try DOUBLE clicking on mpeg 1. Make sure you double click it not single click it. I have a cheap Magnavox dvd player that plays my svcd's beautifully, so I don't think it has anything to do with highend versus low end. Doubt any of this will help. But it can't hurt. Will

Yeah, I'm sure those things will work. I'm just a person who is obsessed with having things perfect (I.E. complying to SVCD standard by using 44.1kHz audio even though 48kHz works, or using the header trick...). Are there any disadvantages to doing any of these things? Thanks again guys

No there are no disadvantages.. If you have TMPGENC you can easily do the header trick. Or you can change bbmpeg. This is something new added to the latest version read your read me file that came with dvd2svcd. ""- Enhancement: You can now encode in MPEG2 but use MPEG1 (VCD) when muxing and authoring. This should help some who can't watch SVCD's only VCD's on their DVD (I know Panasonic can, using this method). All you have to do is go into the bbMPEG tab, dropdown the bbMPEG advanced features and doubleclick on MPEG1."" Now I have not done this myself, but I just got the new version and if it works it will be great instead of making a second step with tmpgenc. And all the chapeters are in place. I would always downsample your audio to 44.1 so that it will play in dvd players such as the sony in sync. Good luck

Try:

--- TMPGEnc ---

VBV Buffer size = 224

--- bbMPEG ---

Movie offset seconds = 0

Output Settings:

I recently tried ripping Harry Potter and the Chamber of Secrets from DVD... I downsampled to 44.1, and burned it on 3 SVCDs. I tried it on two DVD players (Himage - whichs plays literally EVERYTHING, and a JVC). The Himage had the same lag problem, audio was desynched by I'd say a 1/4 second. The JVC played fine... If I am doing something wrong in the encoding whether it be with BBMpeg, or whatever, wouldn't that mean that it wouldn't play fine on either one? There is somethign that the JVC has (a feature?), that can fix(?) the audio, or the Himage just can't keep up... I need to know! It's driving me crazy I can't keep wasting CDs and waiting all day or night for the conversion to SVCD to take place!

What exactly does movie offset in BBMPEG do, and do I need it? You guys have heard the situation before... My SVCD plays on one DVD player but lags on the other. If I change the offset to zero will it be reversed? (the other will play ok while the other won't?)
