True the filename of the specific (proc).
Standby: Avoid GSOD when tunerMask is not initialized

This could happen when you watching a recording and the box goes to

down the box in the situation another box is streaming. I have to find a
better solution to check the tunerusage later but for now I at least avoid
this GSOD
