Upgraded mythtv system to Fedora Core 6 today. It wasn’t too bad. Had some issues to fix after install but it’s up and running … have tested both recording and playback. Experimented a bit with MythDora but elected not to use it since I was rather concerned about retaining my recording data. It does look like a pretty reasonable tool for getting a “fresh start” up and going.
Tried cloning the OS drive before upgrading to see if I could get it onto an 80GB (currently on a 40) but without success. Oh … and a bonus and a big reason for upgrade was the fact that it now supports the gigabit NIC.
