Ah, After some googling it turns out that MythTVs player tries to 
allocate 16 surfaces, and the memory manager can't simply cope with it, 
since HDTV frames are quite big.

So you have two options:

1) Try EXA acceleration and see if it can squeeze in all 16 surfaces.
2) Bring the problem up on the myth mailing list.
