Switch to a filesystem that uses journaling to prevent lengthy fscks, 
and allows for single partitions.  Switch to a filesystem whose fsck 
application is not so memory intensive, and allows for single 
partitions.  Stop uncleanly unmounting partitions, such that lengthy 
fscks are no longer necessary.  Buy more memory for your MythTV system, 
or failing that, buy a new MythTV system such that you can buy more 
memory for it

Could you give a bit more detail about this system with insufficient 
memory to run fsck?  I had no trouble running a fsck on a 2TB EXT3 
partition earlier this week using my laptop.  My laptop still has the 
same 384MB of memory it shipped with when I bought it over 10 years ago.
