[QUOTE="mm1352000, post: 787022, member: 82144"] No problem - I just hope I can help! :) Okay, that's what I was wanting to check. The TsReader and TsWriter logs, looking for continuity issues and time adjustments, however I've already checked there and I don't believe that is the problem. When you have the appearance of dropped frames occurring but the timing is not consistent (with respect to the source material) then generally it rules out source and codec related issues because playing a consistent source with a consistent software setup should lead to a consistent outcome. This suggests wider problems like driver issues, refresh rate matching, heat, DPC latency, and other unusual things. If I were you, the first thing I'd do is check my CPU and GPU utilisation and heat levels during playback. They shouldn't be sitting too high. Then I'd check my Catalyst settings - ensure all the post processing is turned off, and turn on "enforce smooth playback". Fiddle with different output resolutions and refresh rates. You may also want to consider rolling back to Catalyst 11.4 as there have been various problems reported with later versions (although 11.8 seems better) - make sure you take an image of your current setup before you do that. I mentioned DPC Latency - you can check that with the [URL="http://www.thesycon.de/deu/latency_check.shtml"]DPC Latency Checker[/URL]. See how you go with those things for a start... mm [/QUOTE]
