Ok, I've just started skimming through it and I'm sorry to inform you that it's not in sync, It started out good, it wasn't until Admiral Piett did his entrance talking with Ozzel & co that I noticed it but I wasn't really sure of it until the battle of Hoth got started that I noticed it was way out of sync. A good spot to check it is General Veers line "Prepare to target the main generators". I'll continue to check the rest of the film for you if you want?

Edit: It seems to get in sync a little later though, when the lovely sound of the crasching snow speeder appears, that was strangely absent from the '93 release. Damn, what I have missed that soundeffect! ;)
