Cool. I didn't know that, sadly I only have analog cable :(
>>Freevo is somewhat slower because it's written in Python vs compiled C++
This perception was from about 9 months ago, so it may be much quicker
now. It was also extremely fragile and required a huge number of
modules to be installed which made it a pain to set up. Of course that
was before I discovered ATRPMs. :)

Not going to get into a Python vs Compiled C++ argument. I work with
Java for a living so I know what SLOW is. :D While Freevo may be light,
it's dependencies weren't at the time.

Glad it's working better now. When I tested it, the display took a long
time to switch between menu's and live video. It also seemed to hang.
I used a DXR3 for 3 years as my main DVD player, so I know the hardware
output is superb as you can turn off Macrovision. That's why I was so
disappointed in Sigma. I even bought their new card, but it remains
unused in a draw because of the crap Linux support and the lousy Windows

So you're saying it's snappy now ? I must dig my DXR3 up again and give
it a try. Like I said, when I tried this before, it was pretty slow
navigating and there was a noticeable second lag between video switching
