I, too, have noticed out-of-sync commercials but not nearly as frequent as regular programming. Could it be that since commercials are usually 30 seconds or less that they have less time to get out-of-sync than the longer program lengths?

But, if I quickly change channels and return, they come back into sync (as do the program segments). TTFN, Mark
