You were doing great up until that "it works on everything" part. Plenty of folks have pulled their hair out with Myth in the past and you make it sound like a breeze. Look at the numbers of folks posting here that have given up on it and you can plainly see it's far from easy. I for one hope that this version is VERY good but please, the rah rah it works great stuff can be saved - most of us know better having tried it already.
In
my experience, it does work on every PC I've run it on. It even works on my OSX work laptop.
I have had trouble getting crappy hardware to work, but I can hardly blame MythTV. Once it works, it just keeps working. I think some people may have a hard time figuring out how to install drivers and getting their machine to work in the first place. This is when I switched from Centos over to
KnoppMyth. Installed, detected my new PVR-150, and worked until successive upgrades.
Now I have three and a half computers dedicated to MythTV. One is a recording-only host that connects to the CableTV HDHomerun. One was driving my analog projector until the projector power supply went -- it recorded from the Antenna HDHomerun. Then I have another one with my old PVR-150, which also drives the old TV downstairs. The other half is the master backend and MySQL database with no tuner. I am using Centos, and the atrpms yum repositories.
I just did a channel-scan after my upgrade, and I seem to have more channels, and also the audio channels from my sub-basic Comcast cable feed. I think I get more enjoyment out of harvesting television shows than I do by watching them. Think Captain Kirk's head on a 6-foot screen.
