Hmmm. I think we are going to try a couple of these UDPTechnology cards. They have a nice selection plus a bunch of PCI-Express solutions.
The KGuards cards we have tried have a lot of issues with the picture jumping. I'm not sure if its due to using the Philips chipset or not.
We have also tried the Hikvision cards which have an issue with multi channel playback (syncing the times between playback of multiple videos, CPU usage).
