hi, often i have this problem.
it appear on the fourth receiver (i have a 4-tuner dvb-t card).

if i don't close the windows, when they're many, the program
stop to work and i lost all records i have scheduled.

i don't use timeshift.

it is a bug of the program or something don't work on my card ???

thank to all.

Please set timeshift to 200mbyte. Timeshift always using but very small if user disable it.

is the setup correct like in the photo ???
thank.

No. Please enable timeshift.

is correct now ???

i'm not sure about timeshift mode.
other options are:
1) disabled
2) only current channel in buffer
3) all channels from transponder store in buffer
4) not close device and buffer of old channel when open new. (only professional version).

the other option (like in picture) i have choose,
but maybe you know better what to touch.

remember that i use a quad-tuner device (you see in the picture),
and often i record or i have open 10-11 channels.

thank.

"Current channel" is base more for timeshift. Try it. I hope no more messages.

ps: If you record many channels at once then must be have good and quick HDD.
