Not only is the card I purchased from allthings.com.au identical to the one at pictioneers.com, but their text is almost identical. I'd venture to guess pictioneers is buying their cards at $110 each at allthings.com.au, and reselling them for $150. Just a guess. The software listed is all basic V4L2 software. I personally prefer the V4L2 driver from bytesex.org.. It was just easier to install, and my experiences were the same. Only one channel can be viewed at a time: If I open up xawtv 4 times, I get 4 pictures of the same thing. If I change the channel on one, they all change to that channel. Just for giggles I double-checked the windows software I recieved with my card. It does what my program does, just flips through the channels, and grabs an image (but I have to admit, mine does a much better job using vloopback).
