i'm one of those people that is super sensitive to lips syncing perfectly to what i hear.
I've become so obsessive about it, that, even when engrossed in a new and interesting movie, i can still notice when things fall out of sync in the slightest.
I've tried every possible setting combination. The only setting that gives perfect sync is:
Bistreaming: none
VideoClock: On
Display Settings-> set 24p material to use 1920x1080x32x
23. 23hz bolded because for the longest time i thought 24hz was the proper refresh rate for 24p material
Actually though, things still get out of sync with these settings. If i've started jriver fresh and start to play a movie things seem perfect. The moment i start jumping around in the movie and interface, starting/stopping movies, things go slightly out of sync. Very slightly, but i still notice it. The moment i suspect things are out of sync, i restart jriver and start playing at the same point -- sync becomes perfect again.
Any ideas? I monitor the audio path to see what videoclock is doing and even when it settles down to 1x it isn't perfect unless i restart jriver.
Also, two minor annoyances:
(1) when going back to jriver menu after playing 24p material, it doesn't go back to 60hz (menu navigating is not as smooth).
(2) With Red october standard, after seeking, i get rainbow artifacting until the scene changes. Usually scenes change every couple secs so it is not a huge deal, but kind of weird. Doesn't happen with RO HQ.
My setup:
core i3 2.93 ghz
2gb memory
windows 7 32bit
ati hd 5450 12.6 beta drivers
Panasonic ut50 plasma
