overheating in DVP S9000es?

I've noticed mine is more than warm -- it's hot! It seems only with DVD's, not CD's. When I take a DVD out of it, the disc is very hot. It may be because DVD's are in a lot longer than CD's, so CD's don't get as hot.
A few more things -- Frequently, with just under an hour left in a movie, the frame stops dead for a split section, then continues without problem.
Also, it seems that I have to hit the remote button twice to activate a function other than "Play." Other times, I barely brush my hand across the remote reaching for something else and apparently activate the "Stop" or "Pause." Sometimes I have to hit the power button several times to get it to turn on.
Just before seeing this post, I had decided to call Sony tomorrow about taking it in for warranty check. There's a Sony factory repair place about 40 minutes from me.
It's too bad, because the thing plays great. I run the audio through an Audio Alchemy DTI-EDP combo to my pre-processor and get great 2-channel and 5.1 sound. The picture on my Runco DTV-5800 is also superb.

My dealer also said the momentary pause is the layer change. He suggested, though wasn't sure, that the additional heat may be due to the additonal laser for the video (are there TWO separate lasers?) or the different angle of the video laser, but admitted he was only guessing. He also suggested I bring my remote in and test it on a store model to see about the need to press twice. The problem is particularly noticeable on the open/close and the pause buttons.
Another dealer I saw later in the day, who doesn't sell the unit but personally performs an audio upgrade on the unit by reconstructing the analog stage for $1500 (Yes! $1500! He said it makes the unit a world beater with no need for an outboard DAC), thought it might be because DVD's spin faster than CD's, but he wasn't sure either.
I'm going to call Sony direct on this.
BTW, Lowell, I'm also using all Snell for surround.
