The moving of the LiveTV group to a different harddrive did not help at 
all. Same things happened again except that the back-end didn't say 
"Taking too long to be allowed to read.." this time it was just "Waited 
2.0 seconds for data #012#011#011#011to...". The front-end did the same 
thing as last time.

Does anybody know how to troubleshoot this? Is there some signalling 
going on over the network that I can capture? If I trace the whole 
network traffic I will drown in data. Is this UDP (I assume so)?

Also, I have seen people discussing using an NFS mount to work-around 
this issue. I know how to set that up as far as exporting from the 
server and mounting on the front-end. I just don't know how to make the 
front-end use a local (NFS mounted) directory for live TV and 
recordings. I simply can't find the setting.

Any help is appreciated.
