I Have a Panasonic DVD model no DMR-EZ25EB which is 2.5 yrs old. From purchase we sometimes had a problem recording because the machine said the discs were scratched. But this happened even after buying new discs. Okay to play back but sometimes discs we recorded would say ''scratched'', although new discs used. Now we can't play back at all because each time we try it says there is a disk in the machine which is unreadable,when there is no disc! Can we repair economically?
