Well, I do know that MPEG-4 -> MPEG-4 transcoding broke seek for
a bunch of recent myth versions. I think 0.18.1 in particular is
broken.  The SVN series around 8400-8500 are also broken.  This
particular bug is fixed in the latest SVN.
I have no idea on seeking on a currently recording show; I don't
watch live TV.
I don't think playing/seeking with a MPEG-4 file uses the
recordedmarkup table at all, that info is encoded directly
in the MPEG-4 file.  Yes, I know that's what lots of people 
suggest, but AFAIK, the recordedmarkup table is irrelevant
for MPEG-4 seeking (please, someone tell me if I'm wrong!).
