Speed Bumps in Mitsubishi

[Scunning]

Can anyone help me with this problem? I have a 55" Mitsubishi that has a fantastic picture except for one thing. I get this speed bump effect in the lower portion of my screen when viewing a HD broadcast. For example, when watching a show on HDNET the other day the picture was a flyover of Iriland and as they were flying over the landscape I noticed what looked like a small roll in the picture that extended across the width of the screen... Has anyone seen this and can you recommend a fix? This problem is not noticable when viewing standard def. programming......

Thanks!

Unfortunately, what your experiencing is common with HD programming. If you watch let's say the HD test loop on PBS, you'll see that in some scenes, the picture pixelates rather noticeably, but only in fast camera shifts. I think this is due to refresh rates in 1080i. Not to worry though, because I believe that once recording equipment gets more advanced, this will become a thing of the past.
