If you want to research this you can research INSTAPORT and how that affects devices on the HDMI connections. Instaport talks to devices to speed up switching times from device to device. What other devices do when they are talked to is not up to Samsung.
I have a 32" series IV "B" Samsung tv, and a HT-C655W home theatre/DVD player.
The "B" does not have Samsung's "Anynet".
Yet, the two seem to have developed a link...
If I turn the DVD player on, with a DVD inserted, it will start to load - you can hear the intro music/etc start to play through the speakers.
If I then start the TV (as often happens, or adjust the TV to the DVD channel), the DVD will reset itself to the beginning of the DVD.
Then you get to wait for the intro to play all over again...
It's not a major problem, just very curious how the DVD player can be deciding to operate in that manner!
