Hi People, Jonas I like your never give up attitude. I am running on a 3Ghz P4. At the moment I am running with a very slightly modified driver. I have my remote plugged in and I sometimes get hundreds of messages like the one below: Jan 23 22:01:00 media-desktop kernel: [ 1062.522880] dib0700: Unknown remote controller key : 0 20 I have included a line in linux/drivers/media/dvb/dvb-usb/dib0700_devices.c that eats the unknown controller key and prevents the message repeating, as was suggested by Jonas. >From my mythwatcher logs: [27-1-08 17:02:21] --- Started --- [27-1-08 19:51:02] --- Started --- [27-1-08 23:50:20] --- Started --- [29-1-08 05:41:07] ERROR: Disconnect Detected.

[2-2-08 12:24:58] --- Started --- I have been using the modified driver since [2-2-08 12:24:58]. I have been up for 24 hours with no disconnect. I will let you know how it goes. If I do get a disconnect, I will turn on debugging and see how that goes.
