Marvel might work well for capturing (G400+RRG is very buggy for hw capture in linux in my experience and it's unsupported by mgavideo project). One major problem with linux is tv-out. The only way to get near to DVD-MAX-like quality tv-out is to use mplayer with dfbmga vo driver and directfb. I haven't been able to compile mythtv successfully in gentoo with directfb support unfortunately though.
Windows is pretty much a install&go affair, although RRG and Marvel won't work very well for hw capture in 2k&XP either.

Or am I really missing something here? I know in your first post you talked about TV first and then HTPC second, but for the next year or two I have access to an old TV which is good enough - and anyway want an excuse to build another machine
Thanks for all the help btw - v. much appreciated as I know virtually nothing about all this.
