Actual Write Speed Different than what I Selected

For quite a while I have been using Fuji DVD+R blanks for single layer burning. These are rated at up to 16x so I have been halving the write speed and selecting 8x.

Prior to upgrading to the latest version of ImgBurn, it always burned at the 8x speed I selected.

Now since upgrading it burns at 6x instead of 8x. Even though 6x is not even a supported write speed.

I am just curious as to why this is happening. All my burns are successful.

Any ideas?

Notice that the Write Speed was 8.0x but the Maximum Write Rate was 6.0x. Only for these DVD+R and only with the latest release of ImgBurn. In the prior version, the Maximum Write Rate was 8.0x for the same media.

For all other media, the maximum write rate is the same as the Write Speed.

Is AWS enabled for this media??

[QUOTE=chef;2287998]Is AWS enabled for this media??[/QUOTE]

No. I always choose the write speed for each media I use. Again, this media burned at 8x until I installed this newest version of ImgBurn. Now it burns at an unsupported speed of 6x as you see from the log. And the size of the Iso does not matter. It can be small like this one or over 4gb.

Since the burns are always successful and the DVD+Rs play perfectly in my DVD player, I am not about to lose sleep over this. Just curious as to why the selected write speed changed with the latest version.

Yeah, maybe LUK! can shed some light into this?!

It’s being dealt with on my forum.

someone post a link to the thread for this problem plz?
