youtube video to reaper

[kachaloo2002]

Hi,
I installed Any Video Converter and am able to use it to produce files from youtube. When I drag these files to reaper, though, they play only audio. Yesterday I did succeed in getting a converted video to open in sync with reaper, ( I think just by hitting play in reaper the video popped up) Anyway, it did what I wanted to, showed the guitarists hands, I could slow it down,loop,etc. with reaper controls. I saved the project, but now the video doesn't open, only the sound.

If anyone has a step by step of this with whatever video converter (pref. free, I'd appreciate it.
