When burning many files (several tens of thousands) on LG 4082B DVD-ROM it sometimes writes misleading file system. The disk turns out to be perfectly readable, but the files you are reading from such disk have some 300 excess sectors at the beginning belonging to previus file and miss the same amount of data at the end! It is not a problem to read one such file (using ISOBuster) if you know the amount of missalignment, but what to do if you want to read two, hundred or thousand files?
i would say that the burner does not have any effect on that problem. I looks like (to me) a burning software problem which is not able to handle such a large number of files correctly.
