Well, if you are testing for DVD players, you have to use -f 8, because the other -f settings don't create DVD compatible mpeg2 streams. The DVD standard adds some extension data (allowed by the mpeg2 spec) into the mpeg2 stream, and without the extension data you'll find far more hardware players that are allergic. > For one, I wil create a stream with images displaying a grid, > because I noticed that displaying the dvd on a tv cuts of quite a > large border. Other suggestions? The grid's not such a bad idea, it could be used for testing alignment and scanning accuracy purposes. A colorbars DVD could also be useful for tuning color/tint settings. But the cutoff borders on TV's is normal, and intentional, and designed into the TV sets. It's called overscan, and the amount of overscan will vary somewhat depending on the make / model / age / quality / etc. of the TV set. ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
