I am trying to copy an avi. file from my hard drive onto a blank dvd disk (I have a dvd re writer)with nero vision express 6. It keeps telling me that it won't coppy because they are not dvd files eg video TS_ifo, TS_vub, TS_bup, etc. Also it says "This program requires the file advrcntr2 .dll which is not found on this system".What does that mean? Can any one help?
