I'm using fw v1.07 for my 708a for quite awhile now and ever since I updated my fw to 1.07 I've been hearing weird seeking noises. The sound it makes is very noticable almost like the seek noise my old Playstation 1 makes, however I burn CD, CDRW, DVD, DVDRW just fine. This seek noise did not exist when I was using fw 1.04.
In addition to that there is a very long seek time whenever I insert a DVD+R or DVD+RW disc into the drive (takes almost 15-20 seconds before the disc is detected). The DVD+R and DVD+RW I use are from Verbatim recording speeds are 8x for +R and 4x for +RW.
