Do you mount a backend filesystem on a frontend, and try to watch live 
tv via the mount as opposed to streaming? I was using SMB, but ran into 
the 2GB file problem, so I switched to CIFS, which fixed the problem for 
watching recordings, but you can't watch live tv with cifs. With smb you 
mount with a larger ttl setting, there is no equivalent setting in cifs, 
so the frontend cannot see the file, even though it exists and I can see 
it outside of myth on the client.
