Thank you, Oldschooljedi! Did you make an specific modifications to the script?
As it happens, it takes me ages to just render out a lossless AVI using G-Force's script, so I do not know if I will be able to take this route after all. I shall definitely give it a go though. Thanks for the tip about the subtitles, though I do not think ESB has any, so I should be fine on that front for now. :-)
