I've seen the issue that brownriggd mentions. As he says, it's particularly noticeable on motion shots, especially where the shot is panning. Rather than fluid motion, there's a consistent slight hesitation. Like every other frame is missing in the shot. I've always attributed this to a "digital effect". But now that we're discussing it, I do wonder if this issue is caused by the DVR.
Most of my TV viewing is on the DVR. Over the next few days, I'll view on my TV's tuner to see if the issue presents there as well.
If it turns out to be an issue specific to the CM7000Pal, this could be another reason to avoid this product. Particularly if such transient viewing issues are found to be troublesome. Again, the effect is subtle, but certainly noticeable.
