Hi,

If I start TV recording from EPG without first starting timeshifting, or if I schedule a recording with PowerScheduler, the recorded .ts file is "full of" errors and playback stutters etc. On the other hand, if I start recording while timeshifting, the recorded .ts file can be smoothly played back without any problems.

When comparing the logs I can't see any errors or any significant setup differences between a good recording (timeshifting is ongoing when starting recording) and a bad one. What I have seen though, is that often the signal strength and signal quality prints in the log has low values (somewhere between 20-60) on bad recordings, but more or less always 100 if timeshifting is already started.

I have searched this forum and others, but I haven't found anyone describing this problem, am I the only one that suffers from this??

I have seen this at least since 1.0

For some reason your signal quality is very low when recording. This is also reported when you first start timeshifting, Only when the recording is started it will go to 100%.

Do you have the latest firmware and drivers for you FireDTV?

 

[Dr Didge]

As far as I know, I use the latest FireDTV SW/FW:
HW Ver.: 01.36.02
FW Ver.: 2.4.3 Build 60740
Driver : 4.8.0

Strange thing is that timeshifting always works fine, and also recordings started during timeshifting.

Regarding the signal level/quality values, it seems that it sometimes takes a few seconds before they reach 100, same for recording and timeshifting. I attach a log where I have made a loop after tuning, waiting for full signal values before continuing. It doesn´t seem to affect the end result though.

I don't think you have the newest driver. You could try digital everywhere - Integrated Driver Setup and see if it helps.
