LiveTV/timeshifting problem & plays fine after recording ends

[guho]

I have R5000HDs connected to my SageTV x64 9.2.1 and for some channels I have the problem that I cannot watch them while recording but can watch once the recording is completed. The recordings are .ts files mpeg2.

In the log it says:

i.e. it tries to detect the format using internal and external fmt detectors. It tells me it cannot find valid channel "Not find a valid channel" entry which also shows the correct format of 1080i with ac3 sound and even finds the pid 7302 so why does it not play that channel it detects?

Does it make a difference if I were to use the Sage Demux ? Any troubleshooting help greatly appreciated.
