I decided to play with my PS3 some more because Google locates a couple 
of posts with MPEG2 playback at 1080 working alright under YDL. I cannot 
say why I had such problems when I tested it but it was quite a while 
ago so I think it is time to do it again. One thing I forgot to mention 
earlier is that although it is not under Linux the PS3 supports playback 
of H.264 at 1080 using it's native interface, this includes uPnP content 
via DLHA (although I haven't tried uPnP HD myself) from the network.

I wrote this email right before turning my PS3 on and it seems the video 
decided to die, only random green pixels no matter what I do. Maybe I've 
been having hardware problems preventing it from working as well as it
