I am recording the SD versions on a pvr-250.

Well, I've tried various ways to transcode/downres the shows from the HD
channels and I can get that working well enough for actual Mythfrontends.
My problem is that I am also using some Hauppauge MediaMVP psuedo-frontends
and I can't seem to get a working mencoder or other command to transcode
down and play correctly, i.e. with correct A/V sync and the ability to skip
forward/backward correctly.  Yeah, that's really an issue for the MVP list,
but that's why it's not a real suitable solution at the moment.  Anyone care
to share there favorite command lines to downres HDTV content?

I know I can turn off duplicate checking but that's not ideal either.  For
instance, right now if you turn off duplicate checking you would get about
1000 different copies of "Revelations"...
