I recently purchased my first DVD burner - Sony DRU-800A. With my burner, I purchased Fujifilm 8x +Rs and -Rs. The +Rs being YUDEN000-T02 and the -Rs being TYG02. In viewing the media write strategies in the 800A firmware, the +Rs are rated from 6x - 8x and the -Rs are rated from 4x to 8x. I had already burned a couple DVDs before I learned this information which leads me to my first question. Is it okay/safe to burn the +Rs at 4x or less, or would I get better burns at 6x or 8x?
Also, I’ve come to find out that -Rs burned by my 800A do not play in my standalone DVD player but do in my brother’s. This, I don’t understand. I have other -Rs from friends that play fine in my DVD player. Why would their -Rs work and mine not? The +Rs burned with the 800A play just fine in my DVD player. I’ve attached the quality test results of the +Rs. I’m new to PI Errors and PI Failures and don’t fully understand what I’m looking at. Any help would be greatly appreciated. Thanks.
