[QUOTE=NBR;2409459]well on my drive which is a Lite-On 1673S i can burn @ 4x and i DO burn @ 4x since based on the disc quality checks with Kprobe the PIE’s are MUCH lower in the later section of the disc vs when doing the same thing @ 2.4x burn speed.[/QUOTE]
I purchased my LG DVD Burner last year so I would not consider it that old. I can recall having some minor problems with DL burning before I became familiar with setting the write speed (I was using a different burning software with the write speed set at “recommended”).
Now although this is not related to DL burning, I thought I would tell of my experience with DVD+RW where the supported write speed is either 2.4x or 4x.
If I burn at 4x, the burn completes satisfactorily but when I place the DVD+RW into my stand-alone DVD player, it takes about a minute for it to be recognized and start playing. When I do the same burn at 2.4x, the player recognizes and plays the disk almost immediately.
As a result, I always use 2.4x for DVD+RW DL as well as DVD+RW and have never had a problem since.
