Just a further note for anyone else affected by this bug - whilst there is definitely a driver issue (in my opinion) with the af9015 which relates to an inability to recover from tuning errors and is therefore more of an issue for people exposed to low signal strength, I have managed to work around this in my particular situation as follows:
1) Under the MythTV backend settings, under Capture Cards, for each tuner card, I have set the Tuning Timeout (ms) to the maximum allowed (15000), and under the Tuning Options screen set the DVB tuning delay (ms) to 2000. 2) In addition, under the Input Connections, I have the "Use Quick Tuning" set to "Always". 3) Lastly, this set up seems to work *much* more reliably with the 4.65 firmware than the 4.95 firmware. I hope this helps others. -- You received this bug notification because you are a member of Mythbuntu Bug Team, which is subscribed to Mythbuntu. https://bugs.launchpad.net/bugs/683118 Title: i2c errors with af9015 / tda18271 (V4L DVB) Status in Mythbuntu, Ubuntu derivative focused upon MythTV: New Status in “linux” package in Ubuntu: New Bug description: [67192.619144] dvb-usb: error -1 while querying for an remote control event.
