[QUOTE="SwissBuster, post: 832369, member: 78168"] An update following a completely fresh installation... I upgraded to Win7 and installed only the bare minimum to keep the CPU load down. At first, the performance was disappointing with decent SD TV but bad stuttering on HD TV (but at least it played). I noticed that HD TV was sometimes peaking at 100% CPU... and I concluded that I needed more firepower, probably in the form of a new grpahics card. To my surprise, playing with codecs completely solved the issue - I have stable and stutter-free TV even in HD now. The codec I picked was ffdshow from the SAF6 codec pack (the suggested codec - PDVD11 did not even load for me). CPU load is down to 30% when viewing full-screen HD. Contrary to my observation in 2011, the skin selection does not seem to make any difference now. So, my conclusion is that the codec is the key variable, and there is no alternative but to try various codecs until you find one that works. Of course, it helps to make sure that you don't have useless apps running consuming your available memory and CPU. [/QUOTE]
