I have been using my HTPC for 3.5 years now, all with Mediaportal. In January I "upgraded" to Windows 8. After upgrading to Win8 I could never get hardware acceleration to work on my integrated graphics (Radeon 4250). So this last weekend, I installed a new Geforce 610 graphics card and replaced my two ATi Diamond 650 tuners with 1 Hauppauge 2250 (since I only have 2 PCI-e slots).
Since putting in the new hardware, I've had a weird issue with LiveTV. If I try to view Live TV, without recording, I get sound over my SPDIF optical connection, but my HDTV gives a "Mode Not Supported" error message. If I unplug the HDMI cable from the TV and replug it, I get video ago, but Mediaportal portal turns off the live TV. I can watch Live TV in Windows Media Center and if I start recording the show I can watch it just fine, even if I catch up to live.
I am running all of the latest drivers. I use Lav Filters, and have uninstalled/reinstalled them. I switched back to my integrated graphics card and got the same problem. The preview in the TV-server config does work. I have also tried the Microsoft DTV-DVD codec. I have tried every different setting in my video card driver I can think of, including all possible scaling options.
Looking at the log file, this stood out as weird to me, not sure if it matters, but my TV doesn't support 50 FPS:
"2013-04-10 19:24:24.903639 [Warn.][MPMain(1)]: GraphicContext: NO screen calibration file found for resolution 1920x1080!
2013-04-10 19:24:24.906639 [Info.][MPMain(1)]: GraphicContext: MP will render at 50 FPS, use animations = True"[DOUBLEPOST=1365642319][/DOUBLEPOST]Well, I went in to the Dynamic Refresh rate setting and changed the "TV" setting to be 59.94 and 59 and it seems to be working. I don't know if this is a work around or an actual fix, though. I have never had to mess with these settings before, when I was using my Diamond 650 tuner cards.
