I agree there has not been a lot of programs to test with but I have seen several that are supposed to have had commercials skipped and many are not skipped though some are. TiVo would often not process skipping till next day and sometime not at all be at least when it did, it worked. Getting near end of trial subscriptions so I went ahead and paid for both the guide and skip subscriptions hoping will be worth it in long run. Started having reboot issues minutes later, discovered that whole history and thinking now I just tossed my money.
