Unfortunately, an HD TiVo was too expensive for me in 2007, and none of my friends or relatives ponied up the cash to get me one as a gift this holiday season, so I'm forced to settle with the extremely inferior Comcast HD DVR box. But for you TiVo owners, here's an awesome plugin to easily and stylishly connect your TiVo with your Mac. Showcase is a dashboard widget that, given your TiVo's IP and MAK, will not only show you what your TiVo is up to, but also let you download and decode shows directly from there on to your Mac.
TiVoToGo was shipped almost exactly a year ago for Mac, but Showcase seemingly does almost everything TTG does, and is available in simple widget form for the low, low price of free. A few users say it's a little slow (not surprising, given that it's doing all of this stuff from a widget interface, not a full application), but if, unlike me, you did have people who loved you enough to get you a TiVo HD this year, it's definitely worth a download.
