Good news indeed! I don't have an oscilloscope but I can test it on 2 tv's if you like.

I'm sure more people will be interested in those registers, so if you decipher them, could you share the "human readable terms".

Having 24p support would be great! But there are other ways to make 24p look good on 50i or 60i (without jerks).
- Using a "3:2 pulldown" you could display the video at 60i.
- Or by increasing the speed of the video to 25fps you could display it at 50i/25p.

[PS2] Screenshot support for ps2link

This patch adds screenshot support to ps2link: - screenshot is written to file host:screenshot.ps2 after screenshot command. - screenshot command needs width, height, psm, and base-address parameters. - screenshot.ps2 file uses a custom file format (so ps2 does not need to convert the pixel format)....

We are starting to use developers kit and elf stuff
Do you mean ps2dev, or the official sony sdk?

There is a simple example of how to play mpeg2 video in the ps2sdk (ps2sdk\ee\mpeg). It uses the IPU to decode the video. If you want to use a different codec, you will need a software decoder.
