I have, though I've not experimented as much as I perhaps should.  AFAIR
it definitely doesn't help where the recording starts before the channel
begins transmission.

I think in my case the problem is at least partly due to the way
nuvexport and/or mythtranscode expects to be able to read data for
aspect ratio, resolution etc. from the recording right at the start and
if there is no data, or data incorrect for the part of the recording I
care about, it all goes horribly wrong.  If I could get the data from
the first cutpoint instead I'm sure that would help, but I haven't
worked out how to do that yet.
