Ok. I am at wits end. Why? Well my dad's computer is equipped with a PVR-150 tv tuner. I have originally installed Ubuntu 8.04 then MythTv. That didn't work so I formatted and installed Mythbuntu. Same effect. For the last 3 days I have been searching for an updated (at least to Gutsy) HOWTO for setting up my TV Tuner, then MythTV for 8.04. Anything you guys need in terms of specs, just ask.
Oh and if anyone can double check for me on what Tv Tuner is in my dad's computer (which is a SONY Vaio VGC-RB57GY) and tell me if it is compatible with Ubuntu, it would be much appreciated. Thank you guys for all your help!
