Hi, I was attempting the same modification, so I'm glad you have it working.
Well done for finding the firmware on the aver CD! (I had a look about but didn't manage to identify it.) I haven't recieved a reply from aver yet. Are you considering building the i2c sniffer? if not I would be willing to build one and post the data I collect. I can easily handle building the device, the only question is, where do I connect it to monitor the activity on the dvb-t card? ;) thanks, rob On Tuesday 18 November 2003 9:07 pm, Holger Waechtler wrote: > Martin Stubbs wrote: > > Holger > > > >>>>I have my Avermedia DVB-T card working successfuly with Mythtv but I am > >>>>finding that the reception performance is poor when I compare it to the > >>>>performance under Windows. > >>>> > >>>>When I use tzap I get the FE_HAS_LOCK message maybe 50% of the time on > >>>>the best Mux.
