yes and no. Some are shows from BBC/Sky One shows that I don't get
here. Some are shows I downloaded before I had a MythTV machine, some
are shows I ripped from my TiVo, etc. Most of which are xvid
transcodes done outside of Myth. So now I'll take my Myth recordings,
transcode them on my other machine, save the output to one of my
archive drives and use my script to import them into the Watch
Recordings list.

I do this because I don't like the built in transcoding to mpeg-4, I
prefer more control over the encode. I could just relink them in the
db but this method lets me more easily import more than what I've
recorded in Myth without having to have two seperate processes as

Eventually I'll buy them on HD-DVD, and hopefully hdd costs will come
down enough that I won't have to transcode I can just commercial cut
and have a huge RAID5/RAID6 array for my recordings so I can keep them
like this until I can purchase them on HD-DVD (or regular DVD
depending on the show).

something I'd live to see as well, just trying to think out some ideas
for how to implement.
