I haven't got anything installed to check GPU load at the moment though, I'll try and find something tomorrow. HWMonitor claims the CPU is at 25c while playing HD tv.I've had a play with the catalyst settings; enforce smooth playback is on, and I tried turning the other enhancements off/on but no difference there.Also tried setting the TV at 1280x720, exactly the same. I forced it to 60Hz as well just to check and predictably the juddering was much worse but I'd expect that. But it did confirm that it's right at 50Hz, perfectly smooth apart from this once-every-few-seconds thing.I tried DPC Latency Checker and it did throw up a huge red bar once every 30 seconds which turned out to be the network card. Disabling that and playing TV was a little tricky seeing as my TV Server's MySQLd is on my nas, but I managed it in the end by starting TV then disabling the network card. With the network card disabled DPC shows a steady stream of all green but it didn't fix the issue sadly.So that just leaves trying 11.4 cats - I'll hunt for a download link for those tomorrow and give them a try.. 4:30am so getting on for bedtime <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite7" alt=":p" title="Stick Out Tongue    :p" loading="lazy" data-shortname=":p" />My only concern with trying those is they won't have support for this CPU/GPU combo - it's actually an APU, one of AMD's new Llano offerings (aka Fusion). Anyone else have one of these and have it working 100%?One thing I've noticed in shift-1 output is the Measured refresh and Act FPS both sit at around 49.873 on 25fps (50Hz TV setting) content. Is this normal? Should they be exactly 50.0 or is this  sort of variation ok? Just watching it now and render time is about 7.2ms, raster offset 16.8ms. I have no idea if these values are good or not.More fiddling tomorrow - thanks for the help so far <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" /></blockquote>
