Hmmm....I'm seeing this too, with mpg files over 4.6 gig in size. I can import files smaller than 4.6, but can't import a 4.6 file, getting a file format unsupported error. Is this what you see too?
Do you have DVDA 2.0 installed in this machine?
It only appears to be limited to mpg files, as I've inserted several files of 20 gig plus to the media bins. Media bins don't actually "hold" media, they are pointers to where the media lives. But there does seem to be a restriction, I'm wondering if it's related to the size limits of a DVD5, since DVDA can't author DVD9, hence the question about DVD Architect being installed.
maybee it is a windows paging file problem the max is 4098kb + 1 gig ram= 5 giga. in this case the main concept guys progammed something wrong ?
im trying to make the paging file bigger.
maybee the mpeg files are read to ram o virtual mem( paging file) whether the avi`s etc are read directly from HD....? who nows?
main concept is the developer of this part of vegas, or a i wrong? now with the cheap EVE software of theese guys i can load all the files into the bins....
