sceMpegAvcDecodeDetail is overwriting 8 bytes (0x08B9EAFC-0x08B9EB03) of the ringbuffer structure.
As this is a very old game (PSP_SYSTEM_VER = 1.50), I guess that an older version of sceMpegAvcDecodeDetail was returning less data. I need to further investigate in this direction.

I've implemented the change for sceMpegAvcDecodeDetail in commit 8917271.
