Anyone dealt with the above...I received a couple of months a go a innovatek 7" motorised screen and it came bundled with a 6 disc dvd/cd/vcd changer. On the website and the box it claims they can communicate through the IP bus cable. I have tried this and it will not work at all only through normal RCA's, except the remote controls are the same so you ending doing something on the screen and on the changer, anybody any ideas.
