I have been using these cheap silver top dvd-r discs and i can burn with nero but almost to the end of the movie it starts this pausing and skipping. I thought it was a speed issue so i dropped the burn speed in nero 18.104.22.168 down to 2x and it made no difference. i have princo 4x and 2x white top discs that burn fine. I tried finding the media code for these using dvdinfo and there doesn't seem to be one. On the princo ones it comes up with all the info but these silvers don't have hardly any media info. Firmware is V0050. Drive is Emprex (BTC) 1004.
