I have purchased some of the as well. I originally used then on my Panasonic DMR-E20 DVD Recorder. They work great until the end of the disk, about 80-90% through my video freezes or bad pixellization. Upon inspecting the dvd-r's closely, I see small dots that are like the laser missed for a second when burning. So, I decided to try them on my Pioneer DVR-A03, seem to have the same problems. Is anyone else having this problem? Thanks
