slow crappy HR and those sad Clients.
It is amusing. When I got my first DVR it was a Sony-branded DirecTivo which seemed very snappy. Over time, it seemed to get slower and slower, so I got an HR10-250, and it was good for a while, and then started to seem slow. Eventually, a software upgrade made it much faster again.
Then I got a SA8000HD from the cable company running Passport, which was fine, and I could use an eSATA drive to get extra space. They "upgraded" us to Navigator, and it was as slow as molasses.
So, I switched to Dish, with a 722 and a 622, both of which gradually got slower with each software upgrade.
Then I switched back to DirecTV with HR24s, which seemed blazing fast at first, but the new black menus made it slow.
I got an original Hopper with a Joey, both of which slowed over time to the point they were painful to use at times. (see a trend starting here?)
Next, I had a Tivo Roamio OTA, which has not been part of the pattern at all, despite a number of software upgrades and new features which could have easily slowed things down.
Now I have an HR54 and a C61k, which seem plenty fast, but I am sure they will slow down over the next couple of years I have D*.
Aside from the retail Tivo, every STB I have ever owned/leased has become sluggish.
