speed problem with new DVD, especially with ISO files

[scarlac]

Hi

Just bought the DVD RW AOPEN DUW 1608 16x +R/-R DL channel. I have a strange problem with it. When I burn a normal DVD, data or video straight from the hard drive. It burns perfectly at max speed. When I burn an ISO file, it seems like it is beeing burned at single speed. It takes more then an hour to burn it, even when I asked Nero to burn it at max speed or any specific number of speed. It always burns very slowly.

Look at the screenshot I added:
- it's already burning the DVD for more then 13min
- still has to burn for 30sec
- it burns at 4x
- And i have burned 23% (507mb) of that disc



Doesn't looks very logic to me.

Anybody any idea how I can get that speed correctly.

Thanks in advance

Let me ask a stupid question. Did you do a "Burn Image"
burn?

Yeps, I did

Hum, it should have burned at the same speed as any other burn. Does it do that with ANY other ISO you have? If it does then you may have to either extract it to files or use Acohol 120% to burn it directly.

your not the only one. I got a DUW1616 and its slow. My DVD+Rs are 8x. Timer when burning says 6 minutes. Those minutes are slow. It takes over 15 minutes to complete. This burner is POS!!
