Upgrading from FC3 in itself will be an adventure that has a good chance 
of requiring a complete overhaul but if upgraded in small steps might be 
possible. Hopefully your recordings are saved on a different drive than 
your OS. In any case you will need to backup your database before 
starting. If you dont already have a graphical package manager like 
synaptic then install it. Edit your sources.list file to FC6 or FC7 
repositories. Start your package manager and tell it to mark all upgrade 
then deselect any kernel or module upgrades you can and upgrade the non 
OS portions of your system. Then reselect kernel and module updates and 
update again. Once you have updated everything do one more upgrade cycle 
to be sure you catch everything. If you are lucky enough to make it this 
far, a mythtv update will be simple. It should handle the upgrade of the 
database on startup and all your recordings will still be there.

Good luck, the new version requires more processor than your existing so 
you may have issues after upgrade. If you are handy with sql and 
compiling source then you can follow the lead of another poster and just 
upgrade xmltv and fix your database.

PS - This is a good opportunity to blow the dust out of the case and 
fans. If your system has been running for a long time its pretty dusty 
inside and is likely getting hotter than it should.
