Hi there A while back I was experiencing problems with transferring music and video from my pc to ipad. I discovered iFunbox and installed it. A google search led me to someone who had had a similar problem and I followed his suggestion of deleting two files in the iTunes Control section of the iPad. Ever since then when I transfer music and video to the ipad they play back highly distorted and choppy. if I play the files on a 3rd party app they play perfectly which means it is not an issue with the file itself. It is just just when using the native music player and the native video player that the playback is distorted. Last weekend I did a full system restore to factory settings but the issue has remained. What was curious was that when irebooted io6 was still there and didn't redownload from scratch which is what I would think would need to happen as I am sure I need to reinstall the iTunes files I deleted. I know i am at fault here and was stupid to delete files I should not have touched. Is there any way to do a reinstall of iTunes on its own on the ipad or update its system files? Would I be able to copy them across form someone else's ipad using iFunbox? Any assistance will be greatly appreciated.
