Hi, I'm having a problem here.

I'm trying to encode films and stuff I've recorded off TV (DVB-T and -S cards). All the stuff is already demuxed in projectX and cut with Mpeg2Scnitt. I thought everything was going OK, but some are losing sync, it seems to be the films (ie longer) but other than that it seems to be random. The one I really noticed, the audio was fine early, but later was half a second behind.

What I'm doing is
>Setting project to DVB
>Setting encoder to Xvid - Constant Quality
>Setting Container to avi
>Dragging in the video file
>Checking aspect ratio is what I want and then using 'Smart Crop'
>Telling it to encode.

It's not the source, if I just mux the original files together they are in sync.

I tried x264 on default constant quality, but that took 4 times as long and produced a bigger file. And for some reason I tried it on a fresh encode, which was then fine when I tried Xvid.

I know I should have muxed in the temporary audio file with the originals to check it is in sync and then would know it's the video's fault, but I deleted everything in anger.

I really just need this to work now and then learn all the gory details later, my HD is broken and keeps dying, so I need to clear it so I can RMA it and my other is not big enough to hold everything so I'm trying to shrink these to put on DVDs. I was just making DVD-videos which were all fine, but that's a waste of discs and I don't even have a TV to plug my DVD player into.....

Seriously, no-one has any idea, I thought the people here knew about this stuff, aparently not.

I tried it again to the same result, this time I muxed back in the mp3 with the original mpeg2 and it matches, so it's not the audio.

I then tried x264 and it is the same so Xvid doesn't seem to be at fault then either? I did try also to use DivX, but StaxRip won't work, it does the audio, then pops up asking if I want to save the project, which ever I choose (Yes/No/Cancel) it then crashes.

So has anyone anything to say yet? I've just set it off again, but I've chaged 'MPEG2 Source' to 'DirectShow', to see if that makes a difference.

Not having a clue, my only thought is that somehow the video is damaged and drops some frames at some point, I'll have to watch it and try and see when the audio goes out.
