help me build my digital video system

[mert]

greeting fellow fedora users -
I have been shopping for a tivo system and I am wondering if I can build something better myself. Directv wants to charge $200 (or more) plus $5/month for a system that only records and plays back video. I figure that I could build a linux system that does that AND allows recording to DVD AND can be used for web surfing and such for only a few hundred bucks and no monthly fee.
I would like my system to have:
-must be quiet - I don't want to have fan and hard disk noise in the bedroom or livingroom
-wireless remote, mouse and keyboard (bluetooth keyboard and mouse?)
-case with a formfactor that will fit in with other video components
-dvd playback and recording
-cheap! could I build a system for less than $500?
-wireless networking

this system will run fedora linux and I think mythtv is the software that I need to operate it. One of the problems that I need to solve is that our directv satellite cannot be decoded by TV cards so this system will only be able to do recording/playback on channel 3 and the tv tuning will have to be done by the directv box. This might be dealt with with a programmable remote. There is also a serial port on the back of my directv box but I don't know if there is any way to interface with that in linux/mythtv

Any suggestions/advice on hardware, web sites etc would be appreciated!
Cheers

AnandTech (http://www.anandtech.com/) did two articles on building a Linux PVR a few months ago. Here is the first (http://www.anandtech.com/linux/showdoc.aspx?i=2190) and here is the second (http://www.anandtech.com/linux/showdoc.aspx?i=2208). I am sure that you can now buy more powerful hardware than what was in those articles. Good luck.

You will probably be interested in the MythTV project (http://www.mythtv.org/). There even is a Fedora how to. (http://wilsonet.com/mythtv/fcmyth.php)
