Thank you very much Jeff, I will follow your advises !!

Yes, in Photoshop I scaled the images to 2100px the long side (to have room to move it in AE), but i was not sure which format is better; so I tried several: JPG, PNG, TIFF, Targa.

Also, I did a copy in H.264, 1080p for the computer, but the client has the old fashioned idea, than many people going to watch the doc in the computer, using the DVD disc, for that reason he wants to see this play well in both, the TV LED screen and also the computer screen. That is the challenge now.
