[QUOTE="htpcoz, post: 29286, member: 13987"] It seems that any codec that uses hardware accel exhibits the same issues for me. I have also tried the latest Cyberlink, codec (supposedly ATI friendly) and it is a no-go either, also exhibits the same jumpy video. It appears to me like the problem may be related to the hardware deinterlaace, as I can watch channel 7 HD (which is only 576P rther than 1080i) without a problem. However any of the interlace channels are jumpy whenever hardware accel is used (this may also be related to the greater bandwidth). So long as the codec doesn't use hardware accel HD is fine (eg. Dscaler codec is near perfect, although is much more sensitive to stream errors). It looks to me like the old X700 is a bit of a dud for HD decoding (which is strange given the marketing blurb talks about "HD Videoshader"), but hey I guess HD is just another marketing lie :) I'll keep an eye out for any other improvements, but for the moment I think I'm stuck with a (relatively expensive) version of my old Radeon 9200 :( [/QUOTE]
