I have Nero6 program installed on my computer and it's been working great, but lately when I've been trying to burn a file onto a DVD using my Nero I keep getting the following messege for some of my files: Due to patent restrictions, MPEG-4 decoding/encoding is no longer available. To enable the feature along with all other Nero applications you need to upgrade you Nero software. Then when I click on the upgrade message I get taken too Nero website where I have to upgrade my Nero to Nero 7 and pay $64.99 for it. I don't want to pay for a program when I just purchased this one. All I want to know is is there a way to purchase a MPEG-4 decoding/encoding device and does this need to be added to my computer or to the Nero program?
