I have a Linux based DVR, 4 channel H.264 with a 250G SATA HD
Not sure anymore what brand it is, but I bought it on Ebay from a vendor in China. (obviously a mistake) I used it 3 or 4 times and it worked great. The next time I went to use it I couldnt get any video feed from the cams on the monitor. I get the menus and the quad cam screen but no video from the cams.. I've tried everything in the settings even reset to factory specs. email support with China takes 3 weeks for one repititeous question with no results, and they just stopped there emails all together.. I stopped messing with it 10 months ago out of frustration.
Any ideas would be helpful
