HG10 60i - "mosaic" like pattern in highlights
 

Just bought my gear, A1/HG10/Brevis/Merlin+. Everything looks great except for some unfamiliar "digitized blooming" in the highlights of my video. I see it when I bring it into FCS2 and also when i go straight from the cam to my 720p plasma via the component cable.
Any other Hg10 users getting this?

(also, I know other threads have asked about AVCHD workin on an imac. I also just got the new 24" imac 2.4 ghz + 4gigs ram. I put both the A1 footage [24f} and the Hg10 60i footage on the time line and created a 10 minute wedding piece. Everting seemed fine until I tried to do either extreme slow mo or fast motion. The "dropped frame warning came up and had to undo the DMC.)
