Keep the 300g drive with all the recordings in tact.
Backup the database.

mysqldump -u mythtv -pmythtv mythconverg -c > mythtv_backup.sql

Backup the mythtv_backup.sql file, preferably somewhere remote.

Install the 200g drive and install your distro of choice and mythtv.
Setup mythtv just like a brand new installation.  Go through
mythtv-setup, configure the cards, add your line ups etc...   Once you
have mythtv at the point where you can watch tv and schedule
recordings again, then restore the video files and the database.

Restore the database:

I've used this method with great success many times now.

If the disk spaced used for recorded programs is small enough, then
copy them over to the 200g drive temporarily and format the 300g drive
with xfs or jfs if you haven't already.   Otherwise delete everything
else off of the 300g drive and keep the file system as-is.

Mount the 300g drive as /myth/tv, restore the files (if you moved and
formated), restore the database, and you should be back to normal.

IMHO, this will be the cleanest (and arguably the easiest) way to do it.
