I have been using only Divis dvr cards for about 5 years now.
I love them, and I've built about 35 systems using them.
They work great and are very stable if the o.s. and pc hardware are correct.
As for the guy who is using the divis hardware compression borads....
They are great for local recording in real time, but they don't stream video across the network or internet as fast as the cpture or live capture boards.
I can watch video across the internet using a software compression board and have better frame rate than a hardware board over the local network.
The hardware boards use much less of your dvr pc's resources, and allow for non-interlaced capture, which you will only find an advantage when trying do record a license plate on a fast moving vehicle. You cannot get real time 15pfs or above with the hardware boards across a network.
Please let me know if you have any questions. I'll be happy to reply.
