Just one day in and I'm less enamoured with the TV (and annoyed with myself for not taking heed of problems reported by other owners).
Having watched a range of material, from TV, to DVDs, to Blu-rays, there are motion problems across the board, even with 24Hz material. The strange thing is, I wouldn't describe the effect as judder, as remarked by others. Rather, it's like a more subtle version of IFC is at work: every so often, images look like they're on fast forward, no matter what the source. I wonder if this is Panasonic's fix for the 50Hz bug: the introduction of motion processing software to try to mask the issue? Probably not, but in any case the V20 is worse with motion than the G10.
And yes, I can now confirm there are floating blacks, which are irritating once spotted. Already I think I can predict when they'll raise their head (scenes in films with dramatic shifts in contrast being most noticeable).
I'm not sure if the buzzing is any louder than my G10, but I'm now starting to miss the G10's better motion handling and in many respects more stable picture. I'm starting to think my only option is to return the V20, but where do I go from there?
I'd fallen somewhat out of love with the G10, due to its poor upscaling of standard def material and probable rising blacks. My G10's currently sitting in my bedroom, so it's no problem to reinstate it as my living room set. However, my suspicion that black levels had risen and annoyance with its upscaling abilities were the reason I began this whole V20 experiment.
Now if Panasonic could combine the blacks levels and punch of the V20 with the motion handling and stability of the G10, that would be some TV! I'll give the V20 a couple of days to see if it settles down, but I'm guessing the problems noted above won't be masked.
Since my G10 has an extended warranty with Richer Sounds, it might be worth having a chat with them. However, I really don't know if they'd consider rising black levels a problem that would warrant complaint.
Apologies for the lengthy rant, but I'm feeling deflated now. Perhaps I should live with the G10 a while longer and see what 2011 brings.
