Even with the current version of DxTory, the AV sync drifts quite alot on my system. Not a desireable situation :/
(https://dl.dropboxusercontent.com/u/7484348/Screenshot%202014-06-20%2016.38.57.png)
the orange markers at timeline show the "clapperboard" yell & the point where it was supposed to happen. The game-audio seems to be "relatively" in sync (less than 1s off), but microphone/line-in audio drifted nearly 10 seconds during the 4 hour test recording. The game audio was few seconds longer than the video, but after "stretching" to the same length, it was pretty much ok.
I have no idea how fraps keeps this in sync, but it does, so I really wish you could look into this :)

It indeed should be fixed.
As for temporary solution I think you should stop recording 5 hours long footage in one go. I highly you will upload 5 hour long video on YouTube, so you should consider stop the video and start recording again at least once every hour. For example if it's a game like Battlefield, Call of Duty or Counter-Strike, PayDay you play 1 match or mission then at the end stop and start recording at the start of next one. Less sync trouble for you, plus reducing the chance if something happens (e.g. lose electricity) and video will get corrupted that you won't loose all 5 hours of footage.
I usually keep my recordings to ~1h, thats why I said:
Quotetest recording
;)
But even then, the A/V sync is noticeably off
Bump & revival of dead thread.
Apparently, I fixed this! ;D
What I did was:
* disabled dynamic ticks in windows (in admin console: bcdedit /set disabledynamictick yes )
* disabled all cpu throttling , overclocking & power saving features
* MIGHT have disabled HPET (high precision event timer), will edit my post later when I get around to rebooting
* set my line-in settings (thats where my mic is attached to) to be 192kHz/24bit in Window's recording devices
* did NOT change my dxtory settings, still recording 44kHz 16bit stereo for speakers & 44kHz 16bit mono for microphone.
I'm not sure if all of those steps are nescessary, but I'm not going to experiment with a working setup :D
Tested the A/V sync with diablo 3 recording, ~1h 12min in length, and it was perfectly in sync all the way.
edit:
the dynamictick disabling is considered as a debug option in Windows

and afaik it will consume *alot* more battery on laptops if enabled.
