I hope this hasn’t been addressed before. If it has, I haven’t found it. I need to know the best (or your preferred) method for determining the optimum burn speed for a given media and writer. I’d been creating “Discovery” discs using ImgBurn then scanning them in DVD Speed. I was getting mixed results and suspected my 3 year old BenQ DW1655 was having problems so I bought two new burners, a Pioneer DVR-215D and a Samsung SH-S203N. I’d like to determine the best burn speeds for several media on these new drives, but I’d like to avoid spending countless hours and dollars making a bunch of test discs in the process. What’s the best method to home in on the ideal speed? Do you use DVD Speed’s Benchmark, ImgBurn’s Discovery or just try a random image and see how it turns out? Do you start at the max speed and work down from there? Do you do a test at each speed? Should I update the firmware before I begin any testing or wait to see my results with the included firmware first?
An interesting side note. I made an ImgBurn Discovery disc at max (8x) speed for the DL media on the Pioneer, DVD Speed scanned it on the now USB-connected external BenQ and got disappointing results (i.e., 300 PIE). Could be the burn speed. But I then scanned the same disc on the internal SATA Pioneer and the results were slightly better (239 PIE, still not good but better). The drive is reporting its own results locally, whether internal, external, USB or SATA, right? Is it likely that the BenQ is truly toast and not even useful as a scanner anymore? I can’t get jitter and PO Failure stats with the new burners so I was hoping to scan everything on the BenQ.
