Well, I've finished making Arch packages for mythtv and the more important plugins. Working fine so far.
There's a problem with the configure script - setting prefix doesn't work for a rat's ass. Also, I was hoping for some better organization features for mythvideo, like mass imdb lookup and mass category editing via mythweb. Oh well, might have to write those myself.
I am waiting for the entire HDTV thing to sort itself out before I invest in a mythtv system. I like the concept of it, especially for a home theater setup, but I still havent heard much information about getting HDTV from satellite of cable in order to invest the money into yet.
