I have a used KOSS 3101 and have lost the remote. When I put in a home made DVD, I get an error "selection is unrated and exceeds the player's limit" It appears I need the remote to proceed past this - is there any way to manually proceed past this error WITHOUT the remote? Will a Universal remote allow me to do this? Any help would be much appreciated as my 80 year old parents really want to be able to see these converted home movies from my youth!
