I actually have a friend in Minneapolis who couldn't give away his old 
1TB and 1.5TB drives because no-one wanted them I'm in the same position 
and have a drawer of 250gb-1.5TB drives sitting collecting dust. If you 
know anyone like that locally you could copy your files off onto 
multiple "other" drives, rebuild your main 2Tb drive as XFS and move 
everything back.

However....

You might consider me blunt for saying it, but why not just spend $50 on 
a new 2TB drive? All all the responses you've received appear to be 
telling you that yes it can be done, but you risk the data in the 
process. At this point, unless you can get a loan of a spare drive from 
someone, the logical step would be to purchase a spare yourself.

Also....

Why bother? All of my storage is still EXT4 and I've never had a 
problem, so while XFS (and others) may be the "ideal" in some peoples 
minds, I don't personally believe the FS choice will make a massive 
difference to your MythTV experience.
