Mark,
i have a bunch of recordings which seemingly hit something like this.
the trigger point seems is somewhat random - but for the most part it
has been about 90+ minutes into a 2 hour recording after which a/v sync
gets way out of whack (and continues to get more out of sync the longer
it goes on).
i thought it was something to do with mplayer .nuv patches (i use an
xbox as a frontend where i have seen this) ..
i assume it has nothing to do with the length/time of the individual
show that is being recorded, but rather that a "pts wrap" will occur
sometime in a given mpeg2 stream (every 13 or 26 hours if i understand
mpeg2 pts values correctly).
i presume we can add a fix into the demux code also to deal with this
for previously transcoded streams also? i.e. handle the wrap better?
cheers,
lincoln.

This is almost certainly a pts wrap effect.
This assumes you have a mpeg2 recording which hasnt been transcoded.
When it gets in this mode,
use menu, select audiosync, press 0 or 1 (forget which) to do a fake resync.
or apply this patch and see. If you have transcoded the patch wont do
anything for you for the recording you have but will prevent this from
happening in the future..
cheers
mark
