Much lower CPU usage, much faster at handling big files, virtually
unlimited size recordings (with the default 1kB block, ext3 has a
limit of 16GB, I've had recordings well in excess of that size)

You can grow the FS without even unmounting the disk...

JFS or XFS are just much better suited for mythtv is pretty much the
conclusion of every one who analysed the pro and cons...

Now whether it's worth converting your existing FS I don't know ...
but if you were to start from scratch it's a no brainer for me...
