Hi all, I've been delaying my first HDTV purchase due to the rapid change in technology and connectivity issues. But, my 10 year old Panny blew up on me 2 nights ago, so the time is now! I've found a great deal on the Sammy HLP5085W and will probably buy tonight. My question is, on what sources do some people see rainbows? Is it on all sources like DVD,HDTV satellite,cable, or is it limited to one only? I want to make sure I know what to look for while I demo. Thanks in advance for any help. P.S. feel free to comment on the Samsung.
