I have looked a little bit into setting up MythTV for my Slackware 9.1 machine at home. I have yet to buy the tv tuner card because I wanted to see if I could get some advice on the difficulty of setting it all up. The card that I am thinking of going with is the HAUPPAUGE WINTV-GO PCI TV TUNER. It looks to be well supported as far as I can tell (using bttv drivers).
First I was wondering how hard it will be to get the device installed and running using an app like xawtv? I have had problems in the past installing new hardware on an exisiting system. Has anyone had any luck grabbing a new tv tuner (or anything of the sort) and getting the device settings up and running on an exisiting install? I have never had to dabble with creating devices (ex: /dev/video) and dont know how difficult it can be.
Second has anyone dabbled with MythTV setup and would like to give any advice?
Any help on either topic or any opinions would be very much appreciated

Thanks in advance for any posts!
