hi, i am having problems with downloading some discs onto my computer. they are PHILIPS CD-R's and when I try to download them it keeps saying "error downloading codec" and then it only plays the sound and not the actual video (which in my daughters case, is very VERY VERY important) . i was hoping some one could tell me what to do in order to get the discs going. by the way, there are other discs that do play the sound and video and are the same type of disc and were recorded on the same camera, so im assuming that there is a problem with the disc? dont know what to do !! please reply before my daughter kills me!
