Yeah - back in the day, I would be worried, but for $.99, I can usually get
anything I would ever record played on Amazon or Google ro Hule, etc...

I just hate it when my virtual machines ned to snapshot and balloon out and
mythtv does this.

I misspoke earlier - restarting the backend only deleted up to the 100GB
change I made.  I still have a table full of stuff waiting to delete until
mythtv thinks it is acceptable.  I think I will just thrown a could HDDs
internal and raid them and let mythtv have those.  There have been several
times I needed space and mythtv would not relinquish it (a couple
conversations with MTD in the past) and since my lab keeps growing, I will
just segregate MythTV since it seems they are dropping those settings
alltogether.  No biggie - thanks for the feedback..
