I think you will find times when it freezes up, for example, and may require
a reboot. However you should be able to configure something nice and easy
there like the on/off button doing a controlled reboot. Also, it's possible
to accidentally exit mythfrontend and end up in KDE so you'd probably want
to set up a key on the remote to fire up mythfrontend again. Generally,
however, I think it's very useable and stable although it's probably not
going to be as fool-proof as a bought one. My 8 year old son worked out how
to use it for basic stuff very easily. Also, mythweb provides a very good
interface to manager recording schedules etc from another PC.

Depends on what quality settings you choose. Have a look at
http://www.mythtv.org/docs/mythtv-HOWTO-3.html#ss3.1 - it says "Encoded
video takes up a lot of hard disk space. The exact amount depends on the
encoding scheme, the size of the raw images, and the frames per second, but
typical values for MythTV range from 700 megabytes/hour to 2 gigabyte/hour
for MPEG-4 and larger for MPEG-2 and RTjpeg". I have seen a quite detailed
table somewhere that shows how much disk space is required at different
settings but can't remember where it is - must be in Jarod's guide or on
www.mythtv.org somewhere - anyone remember?

It's possible to set it up so that it powere itself off when it's idle with
no recordings coming up and automatically set a wakeup time in the BIOS for
the next recording which will automatically reboot the PC on time. So it
doesn't have to be on 24x7. When you come to this bit nvram-wakeup is what
