In my other reply, I gave some of this info.  Since it comes from another 
computer I had to type it and didn't give all the info like you did above

But I won't have a filesystem on this new linux partition on a new drive. 
The stuff relative to this is down a bit.

No I expect to delete all the existing partitions and create one linux type 
partition.  Then create a Logical Volume add it to the videovg  VolumeGroup 
on hda.  Maybe I create a new VolumeGroup on hdb?

 It would be nice if it were a part of videolv01, but I don't think that is 
possible. I think I can change the configuration of the backend, so the 
recordings sub-directory of /video would be this new mount in fstab. I have 
seen three mount points suggested for Mythv 
data,  /var/lib/xxxx,  /mnt/store and MythDora set it up as /video

This will be confusing to you I am sure since these 2 messages are a part of 
the same thread. They are tied together in my grey cells, maybe I need to 
start over with this info?

Cheerio
