Mobile Encoding for iPod Touch

I'm a long time, but non-expert, user of DVD-RB Pro. The iPod Touch is on the way. In advance of its arrival, I performed my first Mobile encode and have a couple of questions.

1. I chose the H.264 16:9 profile for a 16:9 movie input (and assume that I should choose the 4:3 profile for a 4:3 movie input). Is that the wise choice for the Touch?

2. I didn't spend much time on it, but via XP Task Manager it appeared that only one core of my Core 2 Duo was being used during the encode (my encoding "Speed" was 1.6 on a C2D 6600). As best as I can tell, DVD-RB auto detects dual cores and adds a parameter to the FFMPEG command line to utilize both. Can I determine whether DVD-RB has correctly detected the cores and has set the command line parameter accordingly? If DVD-RB has not done so, can I force the parameter?

Thank you.

1. Yes, that's the best way to do it. DVD-RB will adjust the picture, however, if the movie and the command don't match. For example, if you selected 4:3 on a movie that was 16:9 it will add black borders and the output would be letterboxed.

2. If you double-click on the dialog box's background during the encode, the command line is copied to the clipboard. You can then paste it into a CMD.EXE session and modify it as you wish.

If your system has multiple cores the "-threads x" command line option is added to the FFMPEG command.

Thank you. The DVD-RB H.264 output played perfectly on the iPod Touch. And I made a mistake about the use of both cores during encoding -- both cores were in fact being used. DVD-RB is truly a superb program.
