the problem becomes those times when there's 3 or so minutes of commercials. By the time you have to wait to FF again, you end up doing FF 6 times but due to the lag of getting back that ability you are then often several seconds into the show again already. I'd rather hit FF 3 or 4 or 6 times one after the other and have Tablo understand and as soon as it's ready, having "cached" the FF clicked and have Tablo just go ahead and FF - much like Windows apps cache your key strokes and when the processor is free again, it goes ahead and handles those key strokes you made seconds ago.
It's a combination of waiting for it to buffer, reaction time for the next FF click or touch, etc and you end up either going past the start of the show again, or needing to put up with the last few seconds of a commercial to not miss the first few seconds of a show after commercial break. Tablo doesn't even pay attention to the other FF hits, it ignores them.
