It certainly does, doesn't it.  But, the frontend and the backend are 
both run as the same user.  Just to be sure I tried running the backend 
as root, both with and without setting MYTH_USER, but that didn't fix it.

My mythtv user wasn't a member of the uucp group, but that didn't fix it 

Upon closer inspection, it appears I left out a useful turd in the 
backend log, though:

Couldn't find input: Composite on card
2004-08-13 18:14:25 Changing from None to RecordingOnly

"Couldn't find input: Composite on card" seems wrong.  "Tuner 0" was 
what I was expecting it to use for input.

A quick google search isn't showing anything of interest, so I fired up 
cscope and jumped into the code.  Hmm, "Couldn't find input" seems a bit 
more relevant.  Google revealed that somebody else had a messed up row 
in the cardinput table, a quick look revealed I had the same, so I fixed 
that and now it works!

Thanks for your help.
