[QUOTE="gperkinson, post: 612473, member: 83961"] Hi Ray, Noticed 10.4 has just come out, so I downloaded and installed the latest driver and CCC, however the new version of CCC does not give the option of setting the screen refresh rate to 50Hz which is the best setting to reduce stuttering I could find, so I ended up going back to the restore point. It appears that the "force" option is not available for Vista - only XP in the 10.4 version. I did some searching on the net about this and there were writeup's saying that the Hz and screen refresh rates are not the same thing and that the default 24Hz for 1080i is what should be used. That setting gives a lot of stutter on my setup - when I select [shift]1 the "dropped frames" increase. I understand from your previous comments that you use ffdshow as your codecs and I notice there are a lot of settings in there which recognise the picture size coming through and adjust accordingly - is that correct? The reason I ask is that on Freeview in New Zealand, some of the content comes through in 720 and others full 1080i. The stuttering is worse in 720 than 1080i and it would be greaqt for my machine to resize to full screen. Your thoughts?
