.vro to burn on Nero



Hi Guys
Bought Nero 6 reloaded cos’ threads on the net all over said it could read .vro files from my panasonic recorder. Have also tried renaming as .mpg, but Vision express says “loading”, dialogue box disappears and no file is seen in the edit window, so i assume it has not load, Loading directly into Nero burning rom it says “unexpected file format” Will this ever work, or have i not set something in preferences or other? Nerovision version 3,1,0,25

Many Thanks in advance
