Hi from Texas.. I just bought for the first time a DVR 207 and being technically challenged it took me a couple of days to figure out how to get the thing working. However the trick of transferring images or videos to my computer still has me stumped. When I follow the directions and plug the DVR to the computer.. nothing but an error message shows on the DVR screen.. nothing shows on my computer. .. Any help would be appreciated.. Thanks.. Graydon
