Newegg is offering the
KWorld 340U TV Tuner for only $14.99 after a $20 mail-in rebate. This USB stick-style tuner is compatible with Windows Media Center, and can do both cable and over-the-air programming.
There aren’t QAM drivers available for Media Center (something that will hopefully be fixed by TV Pack 2008… Microsoft still hasn’t gotten back to me on that). However, it does include ArcSoft TV software, which does pick up QAM.
I highly recommend this for anyone with a Vista Home Premium computer. Windows Media Center is one of the few great things that was added in Vista, take advantage of it!
