I am close to getting the DViCO FusionHDTV 3 Gold card ATSC TS stream working. But I can't find the TS stream anywhere. I have written a device driver similar to the or51132 driver, but tailored to the DViCO hardware. Here is what is on the card: Conexant cx23881 PCI / analog capture / DMA controller. Microtune 4042 tuner. LGDT3032 ATSC/QAM demodulator. eeprom that is initialized at the factory. There is no MPEG decoder. What works: Analog TV using v4l2 interface. DVB tuning using scan program. DVB registers the adapter and frontend. I get a timeout error when scan finds a digital channel. I can't seem to get a TS using any of the test programs. They don't report any errors, the just create an empty potput file and never write to it no matter if I tune to a DTV channel or not. I placed debugging messages in my driver hand have verified in two different ways that the LGDT3302 demodulator is locking on to an ATSC signal. I never see the debug message "dvb thread started\n" from video-buf-dvb.c. I suspect this is an indication that I failed to initialize something.
