I'm posting this on both the Mythtv dev and Linux Media lists as I'm not sure where the problem sits, my inclination is it's probably in myth's tuning and I'll explaing why shortly. I recently built a system for a friend of mine, using Fedora 18 x64. Clean build on a DFI Mini ITX P55-T36 system with a decent sized hard disk and 4GB of memory......plenty to run a mythTV backend. The tuners were Hauppauge Nova TD Dual Tuner USB Sticks, USB reference 2040:9580 IIRC. His place has a masthead antenna and no matter what I did I could not get these things to tune properly..... LNA On, LNA Off, Rooftop Antenna, Mini Antenna supplied with Stick, Attenuators in and out, I've messed around with every variation for about 3 weeks now and been unable to get a proper signal on all the muxes no matter what I do. He's in East London on the border of the City near Aldgate. His internal antenna feed to the TV is perfect but I cannot get it behave using Linux no matter what configuration I try. In desperation I finally tried something different today, took in another hard disk and did a clean build of Windows 7 Ultimate x64, didn't touch anything else, installed the latest Hauppauge drivers from their website and used Win7Ult own Media for TV software.....every channel tuned in straight away no problem, except some borderline signal issues with the Film4 mux. Now this got me thinking back to when I first plugged the USB stick in to a Mint Live CD, I tested it using either VLC or Kaffeine (I honest can't rmember which) and I could get tuning on pretty much all the channels straight away. As the device isn't supported properly in Myth/Linux I had to compile the V4L drivers, I'm running Fedora 18 x64 Kernel 3.8.4-202 and V4L compiled last night, using Mythtv from the RPMFusion repos so 26.0.7--18. If anyone can suggest anything I'm receptive to try it but honestly I think something is broken in either the mythtv tuning code or the interaction between the tuners and the V4L drivers. If anyone wants specific info let me know what you need.
