When Hogan's Heroes Season 2 was new and I got it the day it was released in 05 the marks were not noticable enough for me to send them back to Amazon. I ussually send any box sets back to amazon that are not perfect regardless if the discs play alright or not. The discs were able to scan into my computer for backup copies using dvdshrink. Now the discs in season 2 are horribly scarred and are way beyond any couldy issue as my pictures posted yesterday clearly show and will not scan using dvd shrink. Until yesterday the discs have not been out of the cases since the day they were released in 05 when I made up backup copies for them in 05. The next thing I am going to do is run a Nero scan disc for errors on the marked discs and compare them to scans of the discs in season 2 with no marks. Discs 2 and 5 for Hogan's heroes season 2 are perfect and flawless. Discs 1, 3, and 4 are horribly marred with what looks like the disc deteriating and not a cloudiness issue. When I first took them out of the case yesterday, I could see a very faint oil outline of the same patterns on the case it's self that have now disappeared on the case since yesterday. I do not make backup copies of all my tvshows on dvd but Hogan's Heroes is my favorite number 1 show of all time and I did make copies of those so that I could view the backup's and keep the originals prestine in the case, which did not happen.
