I have burned many time DVD videos and everything was ok, but recently some of the DVD that i burned when i put on (i tried on many different) DVD players thay plays not correctly! While the DVD is running sometimes the image get distorted (sure the sound to on that moment). What can be the cause?! I think is the DVD writer problem because i burned some day before some video on DVD disc and it was ok, thereafter (next day) on the morning when it was very very cold i opend all the windows (the windows of the house i mean) to get fresh air, thereafter i burned some other videos and all of those when played on the DVD players it happen many time while playing that the image gets distorted. Could it be the cause the cold, may did it harm the writer?! To be sure that the video files are 100% verified that are correct.
