This was a huge help, Thanks!!!

I can now access the mysql database from the new frontend.  I can also
watch recordings and play live TV.  That is great.

However, I cannot play music or videos.  I can see the titles, but
when I try and play I get a message about failure to open.   I think I
need to enable NTFS on the backend and will try that later today.

The other problem is that XvMC locks up X.  I can play recordings on
SLIM but not on CPU--, for example.  Don't know what is going on

I am thinking of going back to Mythbuntu 8.04 for the new frontend.
8.04.1 is doing some other strange things so perhaps it has problems.
