I bought a HVR-900 today. The sales told me it works with digital TV.
It took me 3 hours to play around with the Hauppauge WinTV software. I download the latest software and driver from Hauppauge. http://www.hauppauge.com.sg/web-content/pages/support_new_xpvista_4.2.html
So far, only analog TV works. Digital TV has channel name, no audio, no video. Beside that remote doesn't work. It very slow when switch analog channels.
Do I have to use cyberlink codec and other third party softwares? Cyberlink power DVD8 US$49.95, DVBViewer $15 Euro. This is almost the price I got the tuner for.
My CPU is quite new. I don't really care about hardware acceleration part at this stage. I just want it to work.
I will try again tomorrow. Not really happy with the hidden cost and the troublesome WinTV software.
