I got my Plextor PX-716UF burner not too long ago.
At first, I was very pleased with it. It was able to backup DVD movies from Shrink in about 5-10 min. It was also able to burn/verify a burnt DVD from Nero in about 10-15min (using Memorex DVD-R 8x media).
Now, it seems to have seriously degraded in performance. It now takes around 20-25 minutes to backup DVD movies of comporable size (where it used to take 5-10 min). It is also taking 30-40min to burn a DVD from Nero (using the same media).
Also, the burning part seems to be leading in with an unusual long lead-in time. Also, it will sometimes take too long and time out (with Nero informing that the DVD device failed). When it does burn, it can do it at a resonable amount of time, but when it switches to verification, it crawls along at 1x (and sometimes even slower).
At the point, I am wondering why I even bought this piece of junk. It is now performing at the level equivalent to my 2x bunrer, which has no problem at all burning/reading.
Any ideas? I have not changed any software/hardware between the time that the drive was perfoming well and now. The media has also been the same.
The drive itself is hooked up to my Toshiba Satelite P25 S607 (which is only upgraded with 1G RAM, otherwise stock) using USB.
