I came across that info from MS. But I didn't change any hardware or move the files. They just stopped working when I upgraded and give me the message "Windows Media Player cannot play, burn, rip, or sync the protected file because you do not have the appropriate rights."
I tried the FreeMe2 program. It says the file isn't protected. Under details of the properties of the file, it says its not protected either.
I don't get it. All my other dvr-ms files play just fine but these three. UGH.
