Hi All, I've got a Compro U500, which is a USB DVB-T stick, based on dib7700 with mt2060 frontend. However, I can't seem to change channels. It is tuned to one channel (which was probably the last one it was on under MS windows), and MythTV always says "No lock" for other ones. Could I be missing something? I wonder if it could be related to this earlier thread about eeprom data: http://www.linuxtv.org/pipermail/linux-dvb/2006-December/014926.html The following is the debug=1 information from the MT2060 driver across three attempted channel changes. The final one is tuning to the "active" channel (the only one that works - I suspect it simply never changes). ===================== Apr 22 01:16:56 harmony MT2060: successfully identified (IF1 = 1220) Apr 22 01:16:56 harmony MT2060: calibration was successful: 129 Apr 22 01:16:56 harmony dvb-usb: Compro Videomate U500 successfully initialized and connected.
