Pinnacle TVCenter Pro software is clunky, slow, glitchy, and a total pain in the a$$ to use. I love the hardware; the little usb TV tuner card works great. The Pinnacle TVCenter Pro software is so poorly programmed that Microsoft used the same programmers to make Vista. Apparently the programmers are more interested in playing W.O.W. than they are at learning how to develop solid and functional software. So far the only alternative software I've found that works well with the usb TV tuner is Windows Media Center... It seems to me that when Microsoft software is better than the software that comes with the hardware from the manufacture, something is clearly wrong. The worse part of it is that Pinnacle TVCenter Pro is up to version 5.4 and still doesn't work right. I'll give you guys a hint, KEEP IT SIMPLE. Maybe you should make a light version of the software. Not everyone needs all the bells and whistles that come with Pinnacle TVCenter Pro. I mean, come on, all I want to do is watch TV. That shouldn't be a cumbersome task. BTW, other than Windows Media Center is there any other software that works with pinnacle TV tuner cards... and works better than the defective Pinnacle TVCenter Pro software that comes with it?
