How do I sync my audio to my video?

Question for Samsung this one.

I have recently purchased a LE32B650 TV, looks very nice. I have encountered the lip-sync problem, lots of threads already dedicated to this so this is a question specific to my setup. If I connect my DVD player using it's SCART (RGB) output to the TV, then connect the DVD player's optical out to my AV receiver the video leads the audio (other threads indicate this is due to processing delays). "Game Mode" reduces the problem but does not eliminate it. Now, I can accept that my DVD player with no HDMI out is a bit out-of-date so I think about replacing it with a Blu-ray player. My question to you is:
If I purchase a Blu-ray player will the problem go away?

I am concerned. My AV receiver does not have sufficient delay capability to cope with this (5ms max). I have noticed that the TV cleverly delays the optical digital audio out to compensate for the video delay, however, as the TV currently only sees analogue stereo via the SCART I loose the HD audio. But most concerningly of all a number of other threads have indicated that if I upgrade DVD to Blu-ray and SCART to HDMI and the TV does see the full HD Audio signal (DTS is my favorite) the TV will still downmix the optical output to 2-channel stereo. Is this true? If so, why?!

How will I be able to achieve audio-video syncronisation without either: A going back to analogue TV, B going back to stereo audio or C buying a new AV receiver with some sort of clever technology to compensate for the inadequacies of the TV?
