I personally can see zero reason why I'd pay to buy a new product for better software. So far as I'm concerned, the problems so far with the Asus box are all pretty much limited to software issues, and I fully expect that they'll fix those. If they don't, and I
have to" buy an upgrade, then I'll look elsewhere. I don't mind buying new hardware for something that it takes hardware to upgrade, like faster CPU, more memory for expanded functions or the like, but for the issues which I have with the HDP-R1, this should all be fixable within software.
If the HD2 firmware will get around the .MKV header compression issue, that's a big reason to move. So far I see one post saying that it didn't and one saying that it will. I suppose that I'm currently annoyed enough to give this a try on spec, so long as I would be able to revert if it doesn't help.
