Which version of xvidcore are you using? The problem I have with softplay is 
with a mpeg2 file that plays correctly with MPlayer using libmpeg2 but only 
gives a black screen with corrupted audio on softplay. Start and stop works 
ok.

I had problems compiling softdevice against ffmpeg CVS. I had to add -lavutil 
in the Makefile. ( Just as info. )

I'm using soft[device|play] and ffmpeg, all CVS of 20050905. No problem with 
freezing at all. Have you tried CVS of soft[device|play]?

Not that much of help I'm afraid but maybe some hints ;)
