You might try, if it still happens with recent v4l-dvb stuff. In that case, Michael Krufky eventually can confirm it, since he is the only one active on the lists currently having such a card. Depending on what other stuff he is working on, this might be still time consuming and an annoyance for him, but maybe he will have a look ;) Btw, I received an used Pinnacle 310i this afternoon, since I'm a little bit stuffed with mysteries on such. First impression on recent: The massive silver remote works, sometimes the driver fails to read the eeprom on load. Else, it has 100% the same reception quality for analog TV and DVB-T like all my other cards with tda8275a and without LNA support and is totally stable. I suspect now, that it is like on the HVR1110s currently, that we might have already different models with and without LNA there too.
