I reinstalled Windows XP onto a new hard drive last week, and then transferred over all of my mp3s, mpegs, jpegs, etc.  I had backed up these files onto a DVD+R.  After transferring these files to my new hard drive, a vast majority of them will not be opened with my software.  In the WIndows Explorer view, everything looks fine, the files are there, they have filesizes, etc...but once I try to open them, I get an "unrecognized file format" error. 

 

Does anyone know what might be going on here?  Could the files have been corrupted somewhere between burning them to a DVD+R and transferring them to my new hard drive?

 

Thanks in advance,
