I have a sony trv27 connected thru the firewire cable to my hp laptop, and have no problem capturing videos into the laptop, but cannot seem to print to tape or preview video on the camera. When i hit print to tape, the proccess actually occures without a problem (it even says printed to tape successfully), but when i check the tape there's no video,just black screen. I've checked the same camera on my dell desktop and everything is perfect, so it must be something else. Please if anyone knows what i can do let me know!!!
