I recently watched Changing Lanes original dvd movie and it completly froze at one point and i had to take the disc out and realized there were no scratches. I thought damn, the original did this, i then realized that its the player that is glitchy and not always the dvd-r discs.
A friend told me that the bulk (OEM,Princo) discs that i as well as probably most buy tend to have minor scratches because each disc is on the top the other, and they are more likely to collect dust on the burning surface than discs bought in cases(retail,Pioneer etc.). the best thing to do is check the disc and spray canned air if possible cause little dust folicles that stay on the disc get burned in the disc when recording and thats causes skips and freezing while playing. THis is what a friend told me.
Tell the world what you think!
