We love the sleek front panel, which boasts a brushed-metal finished, controls for all of the recorder's major functions, and a circular five-way navigational control. A wide section of the front panel flips open to reveal even more recorder controls and a set of A/V inputs, complete with S-Video and FireWire hookups for a camcorder.
Our spirits fell when we got ahold of the remote, however. We're usually pretty impressed with Sony's clickers, but the RDR-HX900's suffers from poor key placement, especially for the playback controls. Even worse, the recording controls are hidden behind a sliding cover and separate from the main controls; to stop a recording, for example, you have to use the hidden Record Stop button instead of the main Stop button.
Sony makes up some ground with its slick, intuitive setup and menus. A setup wizard guided us through the initial settings and channel search, and we got a kick out of the translucent animated menus, which slide across the screen and open to reveal the choices. The system was much easier to use than that of the Panasonic DMR-E95HS, but will still overwhelm newbies with its myriad options.The RDR-HX900's combo of a DVR and a DVD recorder promises all kinds of cool playback and recording functionality, especially given its much-hyped TV Guide On Screen programming guide. So does it deliver? Well, yes and no.
With the RDR-HX900, you can watch a recorded title while you're "taping" another show, but it doesn't always record like a TiVo does. That means you can't pause or rewind live TV, even if you happen to be recording the channel you're watching. And while you can chase playback--that is, watch an in-progress show from the beginning--and watch a recorded title while another show is being recorded, you can't record two shows at once, a feature found in DVRs available from satellite and cable providers but not in any standalone models.
