But again, what puzzles me, why is it much more common(bad at times) than it was in the past?
Because so much new has been happening lately. All these new HD satellite channels and the D10 coming on line - these have all happened in the last 90 days.
You want an example outside of sync issues? Look at all the problems we were having getting ESPN HD 60-90 days ago. It was experiencing pixelization and audio drop outs almost daily. What was up with that? ESPN HD has been broadcasting since 2003. Why all the problems now, especially since they are still MPEG-2. Cable and Dish Network subscribers weren't complaining about ESPN HD, only DirecTV subscribers. It had to be internal with D* and my bet is they were moving things around, getting ready for the launch of the new stations. Something screwed up and we had problems. The engineers at DirecTV identified the problem and fixed it. You don't find posts about how people's ESPN HD is bad anymore.
I will make a prediction here. In another 90 days, we won't see new threads like this one pop up every few days. Sync problems will go back to being rare or at least isolated. The easy fixes will have been made and those will take care of the majority of problems.
You've got to give people time to fix this. I wouldn't be surprised if it also took additional hardware in some of the uplink locations. If so, it needs to be purchased and installed.
My guess is behind closed doors, people at DirecTV are as surprised as you are over the magnitude of the sync problems they have encountered bringing D10 on line.
