I have been doing this for four years and more and I can't seem to find a computer that will capture video without having some kind of problem, like dropped frames. I had a solution to this problem with my other computers. I would use two VCR's. One VCR played the video I want to capture to my computer and the other VCR had a DVD player and I would have the DVD record while I captured the video from my vcr to my computer. I never had any problems whatsoever. I could capture old home movies on big reels for 2 hours straight and not have any problem, yet the new computer I am using can't go more than 4 minutes without doing something like dropping frames.
Capturing video worked great on the HP 2000 laptops. I had two of those laptops and had no problems of dropped frames as long as I used my method.
Now the last two computers I bought will drop a frame even when using my method. I returned one and I am trying to see if I can get this laptop to quit dropping frames or I will exchange it for another.
I am using a HP Pavillion with AMD.
processor - AMD A8-6410 APU WITH AMD Radeon R5 graphics 2.00 GHz
Installed RAM - 4.00 GB (3.44 usable)
