Hi.
Recently "Preview selected cell" partially stopped working for me. ImgBurn shows only the first frame of a cell and doensn't show more at all. Sound plays good.
I suspect that the cause is Nvidia 191.07 XP videodriver. In Vista x64 with 191.07 driver "Preview selected cell" function works as expected.
When I use standard input in Build mode, ImgBurn 2.5.0.0 tells me how much space is available in bytes.
In advanced input mode ImgBurn burn tells me that I have 4.38GB free - I have "Automatic Target Media" unchecked and "DVD+-R" selected s media space.
So where did you see 4.7GB?
As I understand different layer break/end positions come from different gigabyte size. Seems like DVDinfo uses 1024*1024*1000 byte gigabyte (thousand of megabytes) while BurnPlot uses 10^9 byte gigabyte. OptiDrive Control has proper 1024^3 byte gigabyte.
