I own 40PFL6606 and xtreamer, many times i encounter problems with lip sync specifically on this TV.
I saw somewhere a recommendation to turn off the natural motion,
Natural motion is off and only clear LCD is on. The thing is, although the xtreamer is set to 24p, i don't see the Clear LCD working at all (the 100Hz feature). only in SD connection i see the 100hz working.

So the two questions are:
1. how can i solve this lip sync issue
2. how can i enjoy the 100hz which doesn't seem to be working with xtreamer at all.

Note that when using another 100hz TV brand, i don't get those problems.
