I would normally suspect the media, but Sonys are pretty decent. It could be your DVD player, so try playing the DVD on your PC or a friend's DVD player. If the skipping still occurs, I'd try burning at a slower speed - maybe 4X. Always rip the DVD to your hard drive first, and then burn from there. And make sure you turn off programs like screensavers, anti-virus apps, and don't run any other programs while burning (if you surf the internet while burning, maybe you should just wait the 13 minutes).
I never burn any faster than 4x myself,but alot of people in here do and with success.
As long as your using good media,that shouldnt be the problem.Unless you use hacked firmware, and burning faster, than the speed rated on the disc.(not my words, but words ive read from others on here about burning faster)
I have a pioneer burner that will burn at 16x, but Ive never had her over 4x.
