I've recently put together a video from clips mostly taken at 1080/50p on my camcorder. Preview and rendering work fine. If I produce a video using H.264 AVC M2TS at 1920 x 1080/50p this works and plays back fine. However, if I produce a video using Windows Media Video 9, either full HD or even at a much lower resolution, playing it back is awful. On my PC the video is very pixelated and blocky. My HDI Dune media player won't play it at all and crashes, yet it is fine with the M2TS file. I did produce another video to wmv format a few months back which worked fine. However, since then I have added a second monitor to my PC and changed my main hard drive to an SSD by cloning my original HDD. I can't think why this would affect wmv renders and not M2TS renders but you never know...........
Any thoughts and suggestions would be much appreciated.
Thanks
