I'm still using version 0.19-fixes, and the part of my family that
could stand to learn to work a new remote had no problem with this.
Make sure you create some sort of script to restart MythFrontend when
it crashes, and no problem.

I actually happen to have a softmodded XBox that I was using for a
front-end for the longest time. There are pre-made XBox disk images
somewhere out there on the internet, they measure about 1 GB in size
for the primary partition, and 256 MB for the Swap drive. Finding a
gig and a quarter shouldn't be too hard. The biggest problem with the
XBox front-end is that the limited RAM makes it a little slow,
transitioning from menu to menu to playback. However, if your kids
are patient enough to sit through a half second delay, they should be
patient enough to work the menus.
My only concern is that you're probably likely to use 0.20 (is there
newer? Like I say, I've been out of the loop for some time), which
utilizes OpenGL painters, something the XBox can't take advantage of.
There's still options for non-OpenGL painters, but I'm not sure how
they work, or what the performance hit will be.

The XBox is actually quite quiet if you can get its fan down to about
80% power. That'll keep the temperature stable, and the machine very

Last I checked (admittedly, that was a while ago), we have Sky
modules and such, but assuming you need your Sky box, you're going to
have to make sure you have an IR blaster. Some Hauppauge PVR cards
come with them, and even if you don't get one, they're quite cheap.

My machine is a Celeron 600 MHz machine with a PVR-150. This machine
can play back, record, and delinterlace simultaneously. Yours should
be just fine.

I'm assuming we're talking DVB-T or DVB-S here? There's plenty of
support for DVB-T, not sure about S though.

I've heard that some receivers work well, but you'll have to do some
research to find out which.

More RAM, maybe more CPU. It depends on how much CPU ZoneMinder eats.
That is, assuming you still plan to use ZoneMinder. No less than 256
MB of RAM for Myth alone, but with ZoneMinder, maybe a Gig to be
safe. Since this is a multi-purpose box, a Dual-Core CPU would
actually be quite beneficial to you in this case, especially
considering the fact that commercial flagging takes quite a while on
a bogged down system.

The front-end reads the data from the back-end's database and
interprets it, depending on its use (Electronic Program Guide,
recording lists, program searches, etc.). That's all done on the
front-end. No knowledge of the system or its architecture is required
to understand how to make the system function. The Back-end just
records and manages data, the front-end handles all user interaction
