Yet another 605 Question

[jakehale]

I'm gearing up to get the reciever and was looking at the reviews over on Circuit City and someone posted the below:

The ONLY drawback is that when connecting a component source to HDMI out, it will convert the signal to 720P. In my case, I have my cable box hooked up and will not connect via component only HDMI because I do not want the 1880i sources down converted to720P. Although I would like the 480i signals upconverted to 720P, I am not willing to have my 1080i sources down converted. Otherwise a great receiver.

Is that a true statement (not that I truly knows what the statement fully means)? I am only using a PS3 for DVD and a Sony TV that handles 1080..... I really dont want to "down convert".. I was set until I read this persons review.....
By the way I am not a AV pro, very novice at the least and am just looking for great audio and video.

thanks
Jake
