Query: A bad choice for 16x writing

With a destructive toddler in the house I like to back up my DVD movies.Having recently purchased a 25 unit spindle, I recently tried backing up several DVDs with my sony DRU-710A 16x DVD recorder. Although the recording process initially did seem to work smoothly, when I attemped to play back the disks recorded at 16x speed, I would have read errors and lockups on DVD players usually towards the end of the film (the outside of the physical disk, where maximum recording speed is obtained.)I did have better reliability recording at 4x speed and suspect that 8x writes will work fine as well. Given the fact that I paid a premium for this new high speed media, I am disappointed. I have had nearly 100% reliability with Memorex 8x DVD+R, recently making 25 successful recordings in a row with this brand (ASIN: B0001MKU4S)
