I'm having problems with Freeview on Windows Media Center. Up until the 21 November 2012, all channels worked perfectly fine.
Now all channels except for the MediaWorks channels don't work anymore, they just freeze and then WMC tells me that there is no signal for the channel. I'm using a Hauppauge WinTV HVR-2200 MCE on Windows 8 Pro with Media Center 64-bit.
There is nothing wrong with the fact I'm using Windows 8 that's causing problems and neither are my computer specs as TV worked perfectly fine before 21 November.
I'm using a UHF aerial and my lounge TV with a TiVo is connected to the same aerial via a splitter and it still picks up the channels fine so it ain't the aerial. I'm going to upload a YouTube video of the problem soon.
I also doubled the BufferPoolSize to 200 (Hex) or 512 (Dec) in the registry to stop the stuttering and I know that isn't the problem either cause I put that back down to default and it still isn't playing the channels back. I don't know why only the MediaWorks channels work and no other channels do but I'm guessing it's got something to do with my computer.
Also I don't see how this could have affected it but coincidentally I also changed my monitor's connection from HDMI to DVI to prevent to double-refresh when changing resolutions or toggling fullscreen and that was on the 21st as well but I think this is pure coincidence as the channels still screw up on my second DVI monitor (I'm using a dual monitor set up). I hope someone here can help me.
