Hearing static while the dvd

I have the Zenith XBV410 (combo dvd/vcr). I cleaned the lens using the Maxell Lens cleaner kit but nothing happened. Then I ran the Progressive Scan Mode and that seemed to do the trick. Word of caution: Progressive Scam Mode is difficult to turn off so would recommend you remove dvd from player, then press and hold the stop button for a min of 5 seconds up until whatever it takes to disablel PSM (Progressive Scan Mode)
