my videowave video "trimmer" will now not playback any selected file. the utility window opens and appears normal, displaying the original start and end frames, but it will not playback, or respond properly when the handles are moved to a diff position. i have not had this problem before. i am guessing a change in another program that v-wave utilizes for these functions (win media player, quicktime or directx) has somehow disabled this feature in videowave. can anyone help? i have already checked for and installed any available updates and drivers, and have the most recent version of everything mentioned above. I also re-installed the entire mydvd 10 premier suite after updating, but have the same result.
