As TimC said, there should be absolutely no issues with installing and running Img on your system. I too, have multiple burning apps, as do many users and I experience no problems. Img is an excellent app....period

On the other hand, one of the really nice features of platinum is that it's essentially 1 click and the entire process is done, all within one program.

I tried verify in Fab just once, out of curiosity. It worked, but the time it took was just interminable. I've talked to a few others who found the same. I don't know why it takes this long, but there it is.
Having said this, I personally have no interest or use in the verification process. I can't remember the last burn error/issue I had with VSO.

The rare problem that pops up with Fab is on the rip and short-lived.
Just my 2 cents.
