I've checked using simple 2RCA and Jack cable and audio works :D I'm not sure with video because I'm looking for some adaptor from mini usb in my phone to e.g. mini hdmi and RCA video.

I never tried the video input, no reason to think that it wont work, but I do know that the audio inputs work just fine. The multi changer has a mechanical fault which fortunately doesn't affect the electronics.

In free time I'll try to disassemble and check what is wrong with changer, maybe cds just stuck and mechanism is not broken.

Good Luck with that. :)

Thanks :) will let you know about progress
