Let me further explain my previous post as I was trying to respond with a smart phone with a not-so-smart touchy keyboard.
Yes, I ended up choosing the hdv 720-30p under MainConcept MPEG-2 and chose mpeg-2 as output type. It worked perfectly. The quality of the cartoon animation increased dramatically using the 1280×720 instead of the typical DVD resolution of 720×480. I realize the different resolutions are not exact but close enough not to notice.
Pertaining to my original question as to where is the danged option to ‘render using cpu’ only, I found it when I tried to render the .mp4 version and it returned with an error. That option must not be available for all output types.
Guys, thank you for helping me out. And John, I have been learning from you for quite some time. I am always pleased when you respond to an issue because you usually have the answer. You are the king, John. Thanks for being there.
