iTunes version 9 faulty files .
Problem....I have had iTunes for a few years, & the other day I downloaded the latest version plus latest Quicktime. All seemed to go well...but I discovered that some of the tunes in my library are corrupted....(they skip & chatter....slow down etc. ......and the play/stop control is affected when file is playing.) Others are OK. The ones affected are all tunes bought from iStore before I upgraded....latest purchases play fine....so do all other imports. I use Windows XP Home....Soundcard is Sound Blaster Audigy. Drivers up-to-date.....no sound problems in Media Player or RealPlayer. Problems page of Apple Website was no help! I used Windows to repair iTunes....no help. Can anyone suggest solution? ....or even give a URL to email Apple iTunes direct. I could not find one! Thanks, Joe G.
