First I am a newbie to all of this so I am still learning so please bare with me for a bit, but after converting DIVX AVI Movies into a MPEG Format(which when converted are about 3.4-3.7 GB) which *MY DVD* Program can then burn onto a DVD, and then *AFTER* Importing that MPEG over to *MY DVD* it expands the MPEG even more so(about 6-8 GB?), when converting the MPEG I put the BITRATE to around anywhere between 80-90% of the full capacity of the DVD, so obviously after importing this MPEG into DVD it is(MY DVD) expanding the file even more, the question I gues I have is there ANYWAY I can figure the size or even the Bitrate of the file out BEFORE I then use *MY DVD* to burn the DVD?, I hope this made sense because I *think* this is what is happening on why when I try to burn DVD's the option for burning is not highlighted?, Thanks in advance!!!!
