I tried opening a TRP file from an EX7000 for editing in Sony Vegas when I first got the box and had no problems (after renaming it as an .mpg). Ever since then I've not been able to (although they will play fine using VLC). It sounds as if I've changed an option somewhere, which has changed the codec used by the PVR. Does anyone know what I might have done to change the codec used by the PVR??
