You folks must be very forgiving.
Now I've only had my HR20 since Tuesday. What I will say is it ain't half bad. But the general description I have at this time is that it's "clumsy"....for lack of a better word. Why would I even think that to view/manage my SLs I have to go into SETUP?
#1) The Remote: What chimp designed this? You have volume mid remote and trick play at the top. A remote should be handled expertly with one hand without the need to move the remove up and down in that hand. Just look at any Harmony remote or even a Tivo. No real big deal as I have a Harmony 880 and the RC34 is going in the "remote bin".
#2) Trick play just isn't crisp like my HR10, the guide is no speedier and has 2 less channels on it. Maybe after you use the HR20 for a few months or a year you get use to it. But sometimes it seems ok and other times it seems I'm in some type of time delay and things just take longer...or maybe it's just the beers kicking in. Also, the Slip just doesn't cut it.
#3) Already ran into some problem with the live buffer in which I put a show on pause (mpeg2) to fix lunch, came back and watched another 20 minutes before it got to a point it just froze. Thinking about it the point it froze was probably the point in the live show that I came back and resumed playing. I could RR and tried FF and the slip to get past the "dead zone" with no luck. Channel up and down didn't even clear up the problem. Oh well, it was just an old Bond movie and I moved on.
#4) Watched a recorded MPEG4 (local channel) last night and experienced frame shots from the NBC show that was currently being aired while playing the recorded program. I was watching the NBC Nightly news and say frame shots of the 1 in 100 game show. News was recorded at 5:30 and I was watching about 7:00-7:30.
#5) Audio dropouts (1-3 seconds) on SD programming and video pixelation also on SD programming. More than with the HR10.
#6) Wife hates it.
But I'm giving it time. And maybe that's the trick. Over time HR10 users forget how responsive that was. They forget about Wishlists and suggestions. And over time I may too. But as the OP mentioned, I will not forget about DLBs.
I agree with all your observation except I don't understand #4. But other than #6, none of them bothers me that much. I hate the remote but I got used to it. I am glad it does RF so I can forgive everything else. Comparing MPEG4 trick play to HR10 is not fair. I hate the jumpy trick play but it is getting better. For the fact it handles MPEG4, I can forgive this flaw. I do experience some problems, but I moved on, just like you. I finally got to a point that they have to replace my receiver. But my HR10 was worse anyway.
I took so much sh*t from my wife when I switched from HR10 to HR20. Ever time anything goes wrong with the HR20, I get an earful from my wife. After 8 months, she finally said she kind of liked it. I took the chance to tell her that her HGTV and food channel is coming in HD only on HR20. She gave me a skeptical approval.
