thats because this one doesnt use the intrinsic libavformat support. and
only works for avi's
as you saw Isaac is not happy with this one and I can understand why.

I have seen 1 yesterday evening that exhibits this. will track this down.

havent tested with mpeg2 (have none) just mpeg1 ps type files. 3 works ok
with the mpeg1 ps file that Ive tried (1/2 hour ep)
and some avi's (40min ep).
wont need any extra files just yet.
for mpeg2 I may just nuvexport to dvd and test with that. but need to get
avi and mpg support going first.
the other problem with mpg files is that it doesnt seek to keyframes in
libavformat. (yet at least).
I assume this patch will affect how dvd/vcd works/seeks too as it should be
using this functionality if I understand it correctly.
