Just a few tips and a bit of info from my own experience. Please leave your own comments on it. When burning 4x Media at 6x or 8x it is more important not to be running IE or other heavy use applications. So far i have burned unbranded Ritek, RiDATA and Traxdata at 8x. These were all DVD-R. The best results i had were with the RiDATA. One of the Traxdatas didnt work at all, the other worked but during the transfer tests i noticed some discrepencies. RiDATA was virtually perfect. I'll post my media tests on htttp://www.chrismccann.co.uk for 6x and 8x on all three types of discs. I will also be receiveing from Ritek some -R/RW and some +R/RW at 4x as well as the new +R 8x disc later this week or next week. These will also be tested fully and listed. I'll be doing 4 of each disc in the test under the same system environment.
