I am happy someone ask this question because I never get result I try recording USB.
I get many different type of problem.
Sometime I get same error as Guille... rec_not_supported_format for all rtmp streams.
Sometime I get error PVR Error: Error opening channel URL
And sometime it will record normally but when try to play recording back from USB (from stalker recordings menu) the file is does not play and give no error, but file size is good.
I have 200 streams in my IPTV channel list and no channel can I record to USB.
I try different "solution" eg. ffrt2, ffmpeg etc, but nothing fix.
How to do this please? It very important function.
Hope help out there please? :)
