I have been downloading video files for at least 12 months, up until recently I had no problem previewing them prior to converting or burning to a blank disk, I have on my computer Media Player 11, Real Player v10.5, FLV Player v2.0, CyberLink PowerDVD delux version, & Nero 7 viewer player but I am unable to preview any movies at all, can someone give me an idea as to how to get around this problem. thanks I am not a complete novice to IT but I am also not super cluee' either, any help would be greatly appreciated. Merry Christmas to all.
