We've had an HR10 for over a year now, and my wife and I never use the 30 second skip. Pressing FF twice, then play to jump back, works perfectly. You don't have to guess how many commercials there are. I haven't tried this function on the 0xEF update yet, but on the previous version, this definitely did not work as well as the HR10 - maybe because the FF speed (even at 3) wasn't as fast. I'd press FF 2 or 3 times, then the jump back button to go back, it didn't seem nearly as precise as the Tivo unit. We can hit the right spot virtually every time on the Tivo, if we can do a similar thing on the HR20, we'll be thrilled.
