Listen up, Jason Chen. I know your DVR is chock full of 24 and here is the perfect solution to prevent a recording tragedy. The DVR Xpander is really a glorified external hard drive. It can plug into any DVR that has an eSATA port such as the Series 3 TiVo or Scientific Atlanta 8300 (commonly used by Cox and Time Warner). The 250GB model can tack on an extra 140 hours of recording or 30 hours of HD recording and has a $129 price tag. The 500GB model can add 280 hours of recording or 60 hours of HD recording for $199.
