No video in online services

[Podmodder]

I just went into my online services cuz I was bored and thought I would browse what was in there. I have used YouTube in there before and all was fine, but now no matter what service i go to including YouTube I get great sound and no picture. The only thing I have changed since using it last time is adding a client computer in the basement. No settings as far as I know were changed besides adding a network folder as a recording directory so my commercials skip on the client pc. I have gone through all the settings and everything looks fine. I'm pretty tech savvy so this is really bugging me. Any ideas?

Still having this issue and it is now happening to some of my imported video files. Also my .mkv files that were amazing 1080 quality look like they were recorded with a cell phone. If I play them with vlc they are fine so it isn't a codec problem. Please help...
