Ok, I've fixed the DMA problem by enabling an extra kernel option.
DMA is now definitely enabled on my DVD player.  The current situation
is:

1. audio and video no longer cut out without -framedrop, but they are
very out of sync with each other

2. -framedrop results in the audio and video in sync, but the playback
is pretty jerky
