iPod touch Itouch 2g and iPhone H264 format compatible with PSP?

[pectin232]

Using Xvid4PSP 5.05+ for the PSP it works well and if I encode separately for IPhone 2G it also works well. I was unable to find a format which both can play [reducing encoding time and energy costs]. Any suggestions? I use MP4 Ipod Touch it works well for the iPhone but the PSP does not play. Do I need to set the audio encoding which currently is AAC-LC ABR 128k and Video Encoding is set automatically at x264 HQ Ultra. I see several different settings in XVid4PSP like the video encoding portion there are many combination besides the different variations of X264 and AVC levels being unrestricted of do I need to specify the AVC levels 0 to 5.1. The combination are too many. I am sure some do have the PSP and iPhone so I was only wondering if someone had done something similar. Thanks so much
