I have something new to add to the discussion about the framerate/stutter issue.
I have a 32LD550. I experienced the framerate issue while watching DVDs with my XBOX 360. However, the framerate issue went away when I changed the XBOX's output resolution from 1080p to 720p. It's a little annoying that I can't use the 1080p, but what are ya gonna do?
Anyway, I recently put a couple of standard definition movie files onto a flash drive. I then plugged the flash drive directly into the USB port on my 32LD550, and I checked out the movies. Neither movie exhibited the framerate issue whatsoever.
What is the point of my story? Well, I could be wrong, but it seems to suggest that the problem isn't with the TV in general. The problem is really between the TV and the XBOX. The TV doesn't get along with the XBOX for whatever reason (I hope that I'm making sense). After I took the XBOX out of the equation, movies didn't exhibit any framerate issues. I'm going to put a 1080p movie file onto the flash drive and see what happens. I'll report back with the results.
I want to buy a Blu-Ray player. My concern is that there could end up being framerate issues between the TV and the Blu-Ray player.
