I have a strange problem - just wondering if anyone has a suggestion. (or has seen it themselves)
If I start to watch an HD Channel, sometimes, it seems to take a long time before I get a complete picture. It seems like I'm waiting for a keyframe and before I get the keyframe, the picture is complete garbage, including images from a previous show, perhaps seen days before.
It doesn't happen with non-HD. in fact, I don't think it even happens when the HD broadcast isn't 1080p, but really it's most strange.
Usually, I have to stop and start playback a few times before it works - maybe I'm too impatient, but it seems to take a good few seconds while I hear Audio and see blocks, green bits and old images, before the channel I'm tuning to displays properly.
Super strange is that I can be watching an SD channel, but the bits of image that it shows on the HD channel when it's trying to sync is completely different again.
eg, kids watching telly today - I switched to BBC HD and saw an image from the closing scene of the Jubilee concert from last Monday night.. - so a week old image. - Not sure if I had watched any other TV broadcast HD content since then, so that could just be the last 1080p broadcast played.
I'm using a Geforce GT-520 card, if that makes any difference.
