I've been trying to download files in which the speed is listed as T3 or higher. Why do these files always either open pop-ups, or just don't work at all? is there a way tto make them work? also, occasionally I'll open a quicktime video and the window where the video should play is white. I can still hear audio, but I have no picture. a screen appears then telling me to try and download stuff that supposedly will fix this. when I click the link, this page appears full of third party stuff, and I'm curious what I should download to fix this. any suggestions?
