I own an iPod 80GB classic!and was working fine for8 months and until last few days i noticed someting strange when playing videos!There were some lags in video playback for a brief amount of time and then work fine and after 20~40min there will again be lag for 1~3 seconds and work fine! There is no problem with encoding of videos and videos work fine with itunes. I believe that ipod has a 33MHz processor but I never had this issue before.I would be grateful if you guys can help!Thank you!
