Description lordbludwin 2019-01-17 13:47:27 UTC

SUMMARY
TV tuner unable to watch or record a second channel if originally scanned 
using another tuner.

Example: I plug in two usb tuners, select tuner A as my source, and scan for channels, which I then add.
I record channel 1 using tuner A, then attempt to watch channel 2 using tuner B, but am presented with the message "All devices are used for recordings", when tuner B is not in use.

Error only occurs when tuning to a channel that was originally scanned by a different tuner to the one trying to use.

Example: I plug in two usb tuners as before and scan for channels, adding channel 1 using tuner A as the source.
I perform another scan, this time using tuner B, and add channel 2.
I can now record both channels simultaneously.


EXPECTED RESULT
To be able to watch or record a channel as long a tuner is not already currently in use.

OS: Linux Mint 19.1 Cinnamon

Could you please attach snapshots of each tuner's setup screen?

Yes. Sorry for taking so long to return here... I've been busy with Kernel stuff those days.

Instead of "Old device" and "New device", try to use the same name for both tuners. That should allow Kaffeine to think as both as belonging to the same group of tuners.
