"The HV670 contains a DVD drive capable of reading pretty much every type of recordable and rewriteable DVD out there, as well as regular DVDs, CDs, Video CDs. The unit supports the DivX format as well as MPEG 1 and 2, plus JPEG for stills, and MP3 and WAV for digital audio. Argosy has built in Dolby Digital and DTS, and the unit's numerous RCA composite, YUV component and S-video outputs can drive PAL and NTSC displays at 4:3 and 16:9 ratios. There are digital audio S/PDIF co-ax and optical output ports too. Alongside the centrally-mounted DVD unit is the HDD bay. What pops out looks like a typical external PC hard drive - the only difference is the presence of a proprietary connector on the back that hooks into the HV670. There's a mains power jack and a printer-style USB 2.0 port next to it, ready for when you want to hook it up to your PC to copy over video, photo and music content." Almost a great product, but the presence of a "proprietary connector" for the removable drives just kills it. The better solution for consumers would be the ability to just daisy chain USB 2.0 or Firewire dives from the unit. That way we can add any external drive we wish.
