Vincent - Thank you for the review just a few points to clarify if I may.
As an owner of an M87, I've been hugely disappointed by the Freeview Stutter / Judder Fault which I have had on two TV's (so far). I noticed you watched 100 mins+ of continuous footage and did not see any instances of the issue which is superb. I'm just hoping your review sample is representative of the range as a whole and that this fault has been eradicated once and for all.

The other widespread fault remaining on the M8 series is SCART Interference (some call it banding) where horizontal wavy interference lines move up the screen on one or both SCARTS on an affected TV. I attributed this to poor shielding of the SCARTs from the PSU and this was subsequently confirmed by a Samsung Service Centre.
I noticed from your pics that there seems to be much more separation of the PSU from the SCARTs on the F86 based upon the moulding of the back of the unit. Would you say this was a fair observation? Also, before the TV is returned to Samsung, would you be able to please test whether this interference is present using a SCART enabled device?
Coming back to the points made in the review I noticed when talking about the handling of 1080p24 material you stated it was "Noticeably smoother" and that you observed a "reduction in judder".
I'm hoping for the day I see a review talking about no judder on 1080p24 material rather than a reduction. Perhaps my expectations are unrealistic at this stage (or price bracket) with current technology?
Just to clarify this point though, as I'm fairly new to the world of LCD, on Blu-Ray do you still see judders from the edges of large objects such as buildings etc on panning shots? If so, you describe this as reduced, is it reduced enough to be classed as on of the best LCD's currently out there at handling this material (irrespective of the price)?
Thanks in advance for your reply.
