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.
I personally don't care so much about the slow channel changes. I rarely watch live TV. I know some do and for channel surfers the HR series is certainly not going to make you happy.
I do care about inconsistent scrolling through the guide and menus and the delay of acting on remote button pushes etc. The complete 30+ second lockups are also rather annoying!
I do appreciate your willingness to jump in and help!
