Xvid help

Hi. Hopefully someone wiser than me can help me on this one.

Im trying to convert an xvid to dvd so it is playable on a standalone dvd player. I am having some problems though.

When the xvid is converted to dvd, the audio slipps out of sync on the resulting dvd file. This is the case with numerous converting programs.

After searching on the internet for guide, all i can find are guides which involve converting the sound and the video separetly then joining afterwards and THEN burning. This seems like a very long winded way of doing this. So my question being is there ONE utility to do all of this(there must be) or is this the only way?

What is the cause for this 'audio slip'? Is it something to do with frame rates? I should probably mention that i am making a PAL dvd.

Sorry if this has already been discussed, but after a search on here i couldnt find anything.

Thanks for your time.

what are you converting with?

it's becuase the xvid has a vbr mp3 for the sound, because it's not a constant bitrate some programs get confused in the processing

quick way to overcome it is to just try other programs mate

winavi and convertxtodvd have been fine for each one i've tried..

virtualdub can split the sound from the video, then you can give it a constant bitrate, but its a bit of a fiddle to do it and might as well just switch program instead

another thing to note is that you may be tryign to convert a ntsc encoded xvid to a pal dvd with the differences in framerate the audio can get offset.

most dvd players can play ntsc natively so if this is the problem you could try a straight ntsc xvid to ntsc dvd

An audio stream that is of mp3 format can cause the sound to go out of sync with the video sometimes, when you can try is downloading AVIMux GUI in the AVI Editing tools section, strip out the audio stream from the xvid, convert in into .wav file @48000 (khz), and then open your encoding program for the video strean select the xvid, and for the audio, select the .wav file, then encode in the usual way (DVD Flick will let you select different video/audio streams, it is also free).

Open the Xvid and watch the program on your PC, notice at the point of going out of sync whether it is noticeable or if it is only when converted.
Is your DVD player compatible with DivX? if so you have no need to convert to DVD format.

winavi seemd to have done the trick. Thanks everyone for your help.

Also am i correct in saying that a quad core would utilise all 4 cores when encoding using a program such as winavi? So theroetically it sould be twice as fast as a core 2 duo clocked at the same speed? or in the real world does it not work out like that?

(sorry slightly deviated off topic there)

Thanks
