detjstalker,
After you make adjustments in the service menu, I'm unable to assist. I'm sorry, but there's no response I can offer.

I have a samsung LE32A550(asian equivalent of LN32A550).I had some lip sync problems with normal cable after which the service technician came and did some adjustments in the service menu.The lip sync problem has been resolved (so far so good) however I have a feeling that the video is moving a wee bit faster than before and makes movies look a bit weird.NOTE:Motion enhancer has been switched off.I was wondering if the technician has altered the film cadence detection.Can you please help as this problem is really bugging me.
