What i actually meant was that all the mods, and DVD-RB could be controlled from one GUI. Not necessaryily combined into one EXE file. My idea was just to have the different mods all operating from one GUI. Basically the GUI would have a main interface, where it would have the prepare/encode/rebuild buttons, and then seperate tabs for each of the mods to set the various parameters or tweak the required settings. I wouldn't think it would be too difficult for someone to whip up something like that. But since i can't program, i might be wrong. At the moment all it would acomplish would be to stop people having to open several EXE's to encode one dvd. E.g. open DVD-RB.exe to prepare, then close it. Then open the ECL tweaker.exe and do some tweaking there, then close that. And then open the exe for RB-Opt to change a few settings there, and then closing that and opening RB-Farm. If all this could be done from one GUI it would be neater, and easier to do. The programs themselves would still be seperate exe's etc, but they could all be controlled from that one gui.
