Funny you should ask... I found myself catching up on the week's Daily Show episodes on my Divx Connected box even though I have cable and access to Comedy Central. Convenience is king.

I am a major advocate of the D-Link DSM-330 aka DIVX Connected box. Been using mine since August '08 when it was released in the U.S. It has a sexy interface like Apple TV but you're not tethered to the iTunes interface and has an open(ish) platform that allows for plug-in development that includes access to YouTube, Hulu, Google Maps, Weather, etc. The latest beta version of the software (1.5) includes MKV compatibility (excluding DTS-audio) when installed with DIVX 7 but requires a computer with higher horse power than my 3 year old Pentium 4 desktop can handle to run 720p mkv files smoothly (and forget about 1080P). The interface for MP3 playback also leaves a little to be desired but there is a Jukebox in development available on the DIVX Connected site that makes it more appealing. The shortcomings include limited progress on software development (Divx Connected was in version 1.2 when I bought the device last year), wireless G only and not N (improved by connecting to my computer using a Belkin Powerline AV), and much of the GUI sexiness requires a computer with a fair amount of horsepower (which my Pentium 4 is up to the task 99% of the time except for MKV files). All in all, I still think between Apple TV, HTPC's, Roku, Popcorn Hour, etc. I think the DSM-330 packs the best features & compatiblity wrapped in a sexy interface compared to the other options that offer additional playback features but have all the slickness of MS-DOS hooked up to your $2000 plasma.

Looks like an old fashioned grammar dragon fight!

Most but not all.... I bought and quickly returned an AVR-254 late last year after finding myself banging my head against my TV after experiencing tons of bugs/freezing/audio dropouts, etc. Am waiting for the Pioneer 1019 in April.

No FM tuner? Damn.
