i was watching a video on my ipod that i ripped from DVD, and the video froze but the audio continued normaly. so i plugged it into my computer and my itunes, played back the video in itunes from the ipod, and there was no video only audio. so i deleted it and i went through all my videos went to the end of each video to test to see if they worked, itunes crashed when i was in the process. (now once in while some programs do crash occasionaly so it might not be the ipod), but it crashed once. are these bad signs? my ipod is 5 years old.
