Hi all, I hope this is the right place to try and troubleshoot my DVB setup. I have a Conexant based tuner that used to work with the cx88 driver and an Avermedia USB tuner. I have moved house and can't get either of these cards to tune using the scan or dvbscan utilities.
Mythtv is able to pick up the channels when it scans but it can't tune to them later when I try to watch live tv. As it tunes, I briefly see mythtv reporting signal strengths around 40% My TV is using the same antenna (with a splitter) and it picks up the channels and reports 30-33% signal strength and 100% signal quality. Also, I'm not sure I have the right channel file as I live in country Victoria and the closest city is Melbourne so I'm using that file. I would expect to at least tune the major channels. Is this just a case of needing a better antenna or is there something else I can try? (I am already using a signal amplifier at the wall socket.)
