Flashing pink is probably a poor statement by me, what I mean is, as the camera angles changed occassionally when it went to a full-shot of the court you could see the playing field colour shift from green to a shade of pink, then back to green. The players and everything looked fine, just the playing ground would briefly and randomly have that strange effect.
I've not seen it since, but then again I don't watch much live TV. I only really watched the Rugby as I hit over 1300hrs used at the time, and figured it'd be a good test to check on vertical banding and motion again. I literally recorded it on a Youview box in a different room and then hooked that up to my aerial-less OLED afterwards just to watch it off the HDD Library. A bit of a pain, but worth it for a one off.
I see some people rate if you don't see any bands on football and the like then you're probably OK in that regard.
