Is there a single video format (combination of file container, video codec, audio codec, resolution, video bit rate, audio bit rate, etc...) which will work reasonably well on iPod and Sony PSP? And the Blackberry 800 too?

I just returned from vacation with four children. We traveled with two laptops and about 40 dvds for the kids to watch on the plane, in the car and occasionally at night. It was a lot of stuff to haul around. My son already has a PSP and I have a BB-8800. I'm considering upgrading my 3d gen iPod (bw screen, no video) to an iPod Classic (color screen, video support), and/or buying the kids iPod Nanos (also color screens). In any event, I'm thinking I'd like to rip all the children's favorite movies to something which will play on PSP and iPod. Of course, I only want to rip them once. I don't want to have to worry about different versions of "Cars," for example. So, even if picking one single flavor of video would not be the best, I'd still like to stick with one flavor for simplicity. Is there a single common video format which will work? Oh, and I might want it to play on my Blackberry 8800 too.

Apple says that the iPod Nano and Classic can handle these flavors of video:

H.264 video, up to 1.5 Mbps, 640 by 480 pixels, 30 frames per second, Low-Complexity version of the H.264 Baseline Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats;

H.264 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Baseline Profile up to Level 3.0 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats;

MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats

Sony says this about the video capabilities of the PSP:

* Memory Stick -- MPEG-4 SP,AAC

*UMD -- H.264/MPEG-4 AVC Main Profile Level3
Note: "UMD" refers to "Universal Media Disc," the tiny cdroms which psp games are sold on. Blank UMD media is not for sale to the public, so you can't burn your own.

Research In Motion says this about the Blackberry:

# MPEG-4 Part 2 (Simple Profile and bvop, including DivX 4)

* File formats - .avi, .3gp, .mp4, .mov
* Video - Up to 320 x 240, up to 800 kbps, up to 30 frames per second

# H.263 (Profile 0 & Profile 3)

* File formats - .avi, .3gp, .mp4, .mov
* Video - up to 320 x 240, up to 800 kbps, up to 30 frames per second


I don't entirely understand what all this means, but I gather that if I rip everything to MPEG-4, Simple Profile, AAC audio, that both iPod and PSP will display it. Is that correct? I'm not clear whether that will also work on the Blackberry.
