Tested on Samsung Galaxy S

Almost good. You can play a video on a TV with this cable, but:
- The contact is not at the top and moving phone (and therefore the cable) the signal is lost and the transmission stops (time rebouger the cable and reconnecting)
- The picture is not of good quality, very blurry (reading a DivX passing very well by other means living). But it is perhaps the phone is like that (not necessarily the cable). To be confirmed by comparing with a cable manufacturer.
Somewhat satisfied for its rare use and price, but the phone can not truly serve VCR so the quality is degraded.
