I have the Philips 7662 and think the review is a tad harsh. True, the automatic contrast control thing does get annoying (can be turned off), it really isn't bad. Haven't yet tried it with HD, but am going to get PS3 soon and will try it out. Using analogue signal atm (not great but watchable - waiting for freeview) and DVDs which are good.
As I said, I think the review is a bit harsh.
