For my Synchecks in the past, I've always changed out the 9V batteries as well. I always get a very close estimation, but I would then watch something afterwards, and it definitely felt about a frame out of sync. That's why I now start with the Syncheck, and then use a project that I know is 100% in sync (typically using hard hits from SFX as my guide) to finalize my sync check (not Syncheck, haha). It's been great every since.
Whatever you do, possibly do an export of video and audio together and watch it on something like a laptop that won't carry any delay. Basically, eliminate any possible sync "troublemakers" along your chain, and check the vid that way.
One quick note though, I believe that in PT10 (if you're using it), it's been mentioned that if you Bounce to QT with a Video Sync Offset, it will apply that offset to the video as well…so make sure to change that to 0 before you bounce.
