I've got a 3.2 GHz P4 and it plays,  it's just funky - kind of like you 
describe above.

Are you referring to the top_field_first and repeat_first_field flags?

I checked my problem recordings and these flags are set within them.

Recordings where they're unset play fine.

If there's anything I can do to help fix / test this let me know.
