I was a little afraid that there might be a lot of email like there was on the
user list this week. Probably wont be many testing it anyway.
If I did up some Debian packages for Stable, would anyone try them?

This kind of thing can be hard to explain to users.

The patch is installed on my machines and it seems to be working.
It doesn't work quite like I expected. I hadn't realised that the scheduler
would only try other options if it can't record a program and channel/card
priority was minor importance. What it did was keep softstart and softend
for all programs by moving to a lower priority card. I guess this makes
sense because whats the point of recording if it might not have an end. Will
have to update the helptext for schedsoftstart/schedsoftend.

Attached is a patch to get mythweb working. Mythweb displays startts and
endts everywhere so it has no feedback on why difference cards are used.
The next thing is to try the different combinations of overrides, extending
end times and other scheduling stuff. The same applies to mythweb.
Thanks for the time,
