I have a mythtv set up with a TBS8920 and a Kworld dtt dvb-t usb tuner.
Live TV works fine on both tuners
manually recording works fine on both tuners or schedule recording if PC is left on
scheduling recording (using RTC alarm to wakeup machine) works on DVB, but on SAT the recording is pixelated/tearing and is unwatchable. I tested it on both HD and SD channels (BBC1 HD and Ch 4)
I am using Mythbuntu 11.04 LTS
Is this a defective card or is something else going on?
