well, using the patch causes the seektable to be all screwed up, all
my HD recordings from my HD3000 and firewire show 0:01 as the time
length initially. Using mythcommflag rebuild shows some weird time of
hours longer than the recording is and jumping around/fast forwarding
doesn't work. I hate to revert since I was finally getting clean
captures via firewire, but at least I know the problem is a software
issue and not something with the cablebox. hopefully someone will be
able to look at the problem to see what causes it.
