In the latest cvs the default screen size is the video size, so you
don't need scaling.

Well personnally I use MPEG-1, you do not need the DVD resolution.

As I said there are several items to do. I know why audio isn't
working, the current audio decoder is FPU-based and is waaaay too
slow on iPAQ. The solution I see is to use Henri's new plug-in
architecture to create a new audio decoder based on libmad.
As for the optimizations, the YUV can be easily optimized (the code
has already been written for BBPlay, but lacks scaling). IDCT could
be too, but we have to write it from scratch.
Finally, we need a new interface.
What do you want to do ?
