So far, I would say I'm pleased with the box. There are still quite a few bugs that need to be worked out (even with the NR software release). The box seems a little slow when navigating menus/guide/etc although it does seem faster with the HD GUI. The MRV has been my biggest complaint. I don't know if it's because of the H25s or the HR34 but accessing recorded content requires me to constantly press try again numerous times to get it to play. This has become extremely frustrating.
Overall, I like the box a lot. It's nice to be able to have 5 things recording at once with no issues. I realize it's a new box but I was a little disappointed with the bugs that the NR came with out of the box. Things seem to be improving each and every week though so that is a great sign. I'm confident that it will improve significantly in the next few months. I'd recommend getting the box!
