How do you people do this stuff with mencoder anyway? I can't see segmented 
avi writing support anywhere and the damn thing doesn't support avis over 
2GB? Trying to crush a two hour movie into 2GB mjpeg is going to look pretty 
damn crappy at full resolution (that's just my opinion of course). Even in 
divx I doubt it being very good for transcoding.

Does capturing full frames into divx really make sense anyway? I read 
somewhere that it doesn't understand interlacing but thinks the effect is 
just detail which results in something described as very very ugly.
Maybe I'm completely off here but deinterlacing just seems like a VERY VERY 
BAD idea as my target is SVCD compliant MPEG2. And then there's the problem 
called commercials: with divx you have to play around keyframes where as in 
mjpeg you can cut anywhere with one frame accuracy.

And everyone remembers these bt8x8 chips have that nasty color bug that 
appears when capturing half or less vertical resolution (right?) ... so I'd 
certainly want a format that "understands" fields even if my target was 
something like vcd resolution mpeg1 (mjpeg and huffyuv being the only ones I 
_know_ can do that).

So in short: how to get around the 2GB limit?-)
