Although I haven't got MySky, I've been upgraded to a HDMI out MySky box.  Still don't want to pay for MySky so I hooked up my VCR to the RCA video/audio out connections of the MySky box (HDMI out going to the TV) expecting to record a reasonable picture but there are several interference lines across the screen on playback making it almost unwatchable.

I've tried another VCR and different tapes but all show the same interference which I don't understand as the picture from the MySky box thru the VCR is clear (AV input on the TV) is a bit washed out but clear.

Anyone know if Sky have deliberately done something to the video RCA signal out of the MySky RCA to stop customers using the VCR to record - I rang Sky customer service on a different matter and told them I was also going to hook up my VCR via the RCA's to record and was told that she didn't think that was possible so maybe they have?

Thanks

A later form of Macrovision's analog copy protection, called Level II ACP, introduced multiple 180-degree phase inversions to the analog signal's colorburst. Also known as colorstriping, this technology caused numerous off-color bands to appear within the picture. Another form of analog copy protection, known as CGMS-A, is added by DVD players and digital cable/satellite boxes. While not invented by Macrovision, the company's products implemented it. CGMS-A consists of a "flag" within the vertical blanking interval (essentially data, like closed captioning) which digital recording devices search for. If present, it refused to record the signal, just as with the earlier ACP technology. Unlike digital recording equipment, however, analog VCRs do not respond to CGMS-A encoded video and would record it successfully if ACP is not also present.
