Great quality and length
The cable worked immediately after plugging it to my TV and PSP set to output from external display.
The only things that bothered me were that it displayed the XMB main screen in overscan, whether the PSP was set to 4:3 or 16:9. That meant the picture edges were a bit cut off, and that PSP games would not fill the screen, only show up in their original resolution and centered . PS1 games had no problems fitting the screen.
That might be due to my TV's options, though (Samsung Smart HDTV), as I am able to change the picture size to "Fit Screen" from the antenna source, but not from component nor HDMI.
Overall, I am happy of the cable length and the audio/video quality of PSP games played through my TV.
