Fix minor typo in comment.
Skip a bit of work when syncing video/audio.
scePsmfPlayerGetVideoData() writes every frame.

Thought it didn't due to dcache not being invalidated.  Fixes #6085.
Prevent a crash on bogus data in psmfplayer.
Add a delay when setting the psmfplayer file.

This roughly matches the delay that occurs on a real PSP, during which

Check scePsmfPlayerStart() params like the PSP.

Delay scePsmfPlayerStart() when seeking.

Validate and report initial psmfplayer playMode.

Don't allow seeking without an EPmap.
