stormweaverx,
The home theater system may not be sending a supported resolution. Check the manual for supported resolutions, and if necessary, change the resolution that the home theater system is sending.

I have a Samsung series 4 LCD model LA32A450C1 connected to a Philips Home Theatre system model HTS6600/98.
Whenever I scroll the source to HDMI and then wait for a while, the message " MODE IS NOT SUPPORTED " came out. Other functions are OK.
Do you know what is wrong here? Appreciated your advice.
