[ExtractStream] Splitting movies for VCDs?

[Grant Stockly]

Do you need to make a MPEG1 VCD? I'd recomend a divx format. (Wouldn't be 
a vcd...) You can fit more than 2 hours into 650 MB without loosing quality 
and you can split the files without recompressing.

VirtualDub will split movies down to the frame with audio in sync. If you 
select both audio and video to "Direct Stream Copy" and not to 
re-comompress, it is very fast.
