Just yesterday the installer showed up and replaced my two Hughes HDVR2's with two new THR22-100's. They replaced the old 18" oval dish with a new 24" Slimline 3.
The HDVR2's have been in use since 2003. Basicly I got tired of repairing them, the hardware was terrible, the Series 2 TiVo software was great. In 2007 I added a TiVo HD (Series 3) and high gain UHF rooftop antenna to my main TV, to allow me to DVR the literally dozens of digital OTA channels in the SF Bay area. I frequently find that the subchannels contain more compelling content than the main HD channel, which is all that DirecTV supplies via the dish.
So far, so good. The two THR22's took overnight to acquire enough program listings to allow me to enter 2/3rds of my Season Passes. The other third cannot be entered because they are between seasons and do not exist in the program listing, which is a tad annoying.
IMHO the THR22 is an odd amalgum of Series 2/Series 3 features, along with a few unique features. They are the first TiVo's I've had with a visible disk capacity indicator, for example, which I like. (My TiVo HD has not had an update in a long time, and is lagging pretty far behind the Premiere models.)
I don't really care for the bright blue LEDs on the front panel, and setting the display to "dim" hardly made any difference.
Nope, mine is not overheating. The one in the closed wooden equipment cabinet with cooling slots on the back is running at 49C and says "Normal".
The image is great on the dozen or so channels I actually use a lot that are now in HD. I have the old Total Choice Plus package with local channels - not that I need the locals, but they were part of the bundle.
So far, I'm pleased with the upgrade. It's costing me another $5/month, and $343 for the new equipment.
