Many thanks for your reply, all this malarky is wearing me down, I always thought I was quite savvy with PCs but when it comes to this DVD Production faff, it leaves me stone cold.
I have exported a File to folder using the MPEG2 format which it completed successfully although it was huge, something like 5.6Gb, I then tried to use NERO 6 to actually burn the DVD, but that told me it was far too big a file to automatically compress and when I tried using a +R DL (which my burner is supposed to support) that failed as well !!!
I then tried to use DVD Shrink to automatically compress and I couldn't import the MPEG 2 file format. If I had used the AVI format to output from would that have been accepted by DVD Shrink ?
Yours highly confused.
