I'm not sure how you would mount multiple drives at /myth, unless you mounted 
them on directories under /myth (/myth/drive1 and /myth/drive2).

You are probably better off mounting them separately anywhere you like and 
then using the storage groups feature to add them to your system.

Remember that it's best to have your OS, and particularly your MySQL database, 
on a different spindle from the video storage. I say "spindle" because merely 
having it on a separate partition is not enough, the DB wants to not share a 
physical drive with video storage.

How much you can do with a Myth system is very dependent on drive I/O 
performance. This can be increased by things like RAID0 or filesystem tweaks, 
but unless you are transferring several HD streams at once most modern 
hardware will perform well. By "modern" I mean built in the last decade or 
so.

Perhaps we get more satisfaction from a smooth install, but I have found I 
seem to learn more from the things that don't go quite right at first.

Of course sometimes you just want a PVR, not a "learning experience".
