Tuner constantly hangs during viewing live TV. First, only unloading/loading dvb-usb-tbs5923 was helping. Sometimes it hangs so hard, that reloading or even rebooting doesnt help, only cycling power on tuner. Was it a terrible mistake bying USB tuner and it will not work stable, like PCI ?
It happens this way:
1. Watching live TV in MythTV
2. Picture freezes after random amount of time, can work for hours and hours, or can hang after 20 mins
3. When I'm trying to start live TV again, i see that singal is 23-27(constantly changing) and there's no LOCK. If i stop mythtv and try szap, I'm getting "Operation not permitted" error. dmesg shows no errors.
4. rmmod dvb-usb-tbs5923 dvb_usb
5. modprobe dvb-usb-tbs5923
6. Starting live TV, signal is 77, as usual, everything works.
Hard hang happens same way, but reloading drivers doesnt help, only cycling power
Ubuntu 14.04, TBS drivers v151229
Can do any compiling/debugging, if needed, because desperately need to fix this irritating behaviour. Thanks.
