I upgraded my computer in 2011 with Windows 7. I am trying to download videos onto a DVD-R. My computer tells me I need to format the disc first. OK, no problem I can do that....I indicated I want to use a DVD player to Mastered vs. USB flash drive but when I hit next the window pops up that says "Windows can't read the disc in drive E:\. Please help...what am I doing wrong, very frustrated.
