I was having A/V sync issues in Windows 7 with Gotham Beta 1 using hardware decoding and 24p playback. I found that introducing a 1 second pause prior to playback to allow the screen to change refresh rates + the A/V sync option to drop audio packets helped maintain sync. However, an easier solution is simply to enable software decoding. Even without the pause or A/V sync options enabled, I get perfect synchronization. It's worth noting that I don't have any issues on my Rasberry Pi build or MPC-HC in Windows with DXVA or CUVID. In any case, software decoding has always worked better for me in XBMC on Windows, and if you have a fast enough system, it's worth trying.
