My first post! I've lurked for probably 15 years. A DU page has stayed open in my browser for years, I've just never signed up. I read your post and thought, "Well, now's the time." It feels good to be an official DU-er! About your cords:
I can't be sure but I am assuming you have either three or five "RCA" plugs to deal with. They're round with a center pin and a serrated outside connector and about 1/2 inch wide. The center pin is slightly longer than the outside connector. If these sound familiar, then look for a group of three - green, blue, and red. Those carry your video only. There's another group of two - red (again) and white. They're for left and right audio. You'll distinguish the different reds by how they're grouped - the red with the white in a pair of two is audio, the red with the blue and green is video. It's five altogether - grouped in one set of two and one set of three. It then becomes a matter of plugging everyone in their respective jacks and you just follow the colors. If you see a set of two jacks (red and white) and a set of three (green blue, and red) then you're in great shape. Just make sure to put the reds in the right place. Your picture may be B/W because you've substituted an incorrect red plug. There are adapters available if the above instructions don't solve your problem. The Red/Green/Blue plugs are called "Component" video. I just did a search for "component to usb adapter" and saw several for around ten bucks. An easier fix might be an HDMI cable - they carry audio and video. You'll need HDMI jacks on both sides of the equation but it's just one cable. Sorry to be so pedantic and repetitive - just trying to clearly communicate! Let us know if you still have questions - hope this helps.
