2.72SEB Video playback?

I've been having some trouble;

WHen I convert my video files in 3GP Converter (yes, the Asian, most common one), basically ALL of them come up as Corrupt Data on my 2.71SEB. This didn't happen when I still had 1.50 w./ DevHook 2.71. No matter what video it is. Why is this? Is there any way around this?:confused:

This doesn't happen to me. I use 3GP Converter for YouTube flv files. XviD4PSP for about everything else. Videos converted with 3GP Converter come out just fine on my 2.71 SE-B as they did on 1.5, with or without DevHook.
