a quick followup:
went out and bought toast. tried to encode video DVD from mpeg-4 files, which seems to go okay, then when it goes to burn the DVD it gives me something about a "sense error" , says 'sorry, the dvd couldn't be created" and then that's it. I'm using Verbatim AZO DVD-R's which used to work for me okay. Hmmm---maybe bad batch??
I have a stock dvd burner in my Mac Pro
other relevant stuff (or not) OS: 10.9.3, Ram: 10 gig, HD space: 4 TB, video card sapphine HD7950 3 gig VRAM
well, that's it...I'm stumped for right now....any help appreciated
thanks
JB
