The big thing is to look through the documentation on mythtv's site, ignoring the parts about compiling from sources. I found a lot of answers there.
The main steps after getting everything installed follows: (It has been a while, so I may be off on the order.)
start backend as root
follow the instructions that pop-up after that
I had to go back into mythtv-setup and set all the channels to an offset of 105 for the channel freq.
Then you run mythfrontend as root, unless you want to set mysql.txt to be readable by you as a normal user.
Go through and set the recording parameters, and all the other settings to your liking. Watch the live tv to make sure everything is working for that.
Play around with the Program Guide and watch some tv!
Hope that helps.
This is excellent info. I have also toyed with the idea of using Win XP MCE 2005, after seeing how polished it is.
Are the following enough to build a decent HTPC/TiVO?:
SN95G5 (nForce3 250GB socket 939)
Athlon 64 3000 939 90nm
1 gb Corsair Value ram (512x2)
120 or 200 GB Samsung Serial ATA Drive 8MB 7200 rpm
eVGA NVTV (or ATI TV WONDER 550 if the price drops)
XGI Volari V8 128MB AGP 8X As main video card (2D quality is amazing)
Windows XP Media Center Edition 2005 or Linux(?)
Sony 16X Dual layer DVD Burner
Also, what would I need to do to allow this to be HDTV capable, or at least upgradeable to that if it isn't possible to do yet. Thanks.
