Considering that the UTV interface, even with the 3.8 update, is pretty much 2003 technology, it's amazing how well it works - explaining it's loyal user base.
It's a shame, because given what they have, they could have made it even better with a few more simple additions. For example, a repeating manual record would likely have been simple and adding more narrowing options, like more than just 4 time ranges, or letting you select the channels to include or exclude. An option to select recordings based on a regular expression match against the guide data would have satisfied a lot of geek types (but would probably mystify the average user).
But overall, it's really nice and I have no desire for HD. At least not w/o a really bullet proof record function (I have auto-records setup that have been going for 3 years or so).
The utv is the most reliable complex hardware/software combo I own. And I got lots and lots of toys. It just works!
