Hi, i'm working on the rewrite of BurnItNow. I'd like to add full support for DVD writing. If i insert a file bigger than 2048MB inside BurnItNow window (eg a file of 2.93 GB) BurnItNow tells me that this file is of "-1095MB". At the moment BurnItNow can calculate a max size of 2048MB. The calculate function is inside the file JpWindow.cpp http://pastebin.com/M2FLy8hD here the details. I have tried to modify the value tempas = atol(buf) * 2048; But if i modify this value, all calculations become wrongs. Here there's also the full version of JpWindow.cpp: http://pastebin.com/JnSbSh9A how can I overcome this obstacle? Thank you very much.
