[mythtv-users] Error opening jump program file buffer

[Brian C. Huffman]

All,

I've been having a problem for a while now in the .24 branch that when I 
go to change channels on my slave frontend on my HDPVR source, it fails 
and I get a popup "Error opening jump program file buffer" and I see 
this on my frontend:

This is what I see on the backend:

I don't think this has been doing this until I updated to one of the 
fixes, but I'm not 100% positive.  Does anyone have any insight into this?

Thanks,
Brian
