I want to whatch my avi files on my thumb drive through my old vcr that does have the audio video inputs. What can of converter do I need to purchase, or is there one?

Try a media player such as the WD TV Live. Its not the only one out there, but is one I have and like.

Why go through the VCR... hook the Media Player directly to the TV.

Wee, I have an old 1994 tube TV, that's why I use the vcr, its also easier to acces from the front.

Well what I suggested will work... and when you upgrade it will still work for you as well.
