Speed is relavent. For instance, the difference in the time it takes to change channels between a HD DVR and an HD receiver. How long is that ? What would we do with that bit of time if we had it change instantaneous ? Would we get up out of our recliner and go play a game, have a meal, enjoy the company of a lady. Nope, not enough time to really count. OK, let's say that we had instant channel changes. I could go around the guide a few more times per day. Did that get me more or better programming ? No. Did that get me enough time to complete any task ? No. Did it let me go make any more money. No. What did the speed up of the receiver get me ? Nothing, other than the fact that I can now look and say "Wow, that changes channels fast". Whooopeeee. If you do not like the system and have left it, why are you here ? Are you looking for help ? Are you trying to help others ? I am here to learn and to try to help others with some minor problems that can be changed with settings, etc.
