v+ installed today strange problem!!!

[scottystar]

hi guys had my v+ installed today the pvr itself is very good but i have a strange problem its connected by the hdmi lead the vm engineer brought and plugged into the hdmi1 socket on my sony dlp rear projection tv.

every now and again it kinda swicthes off and the info bar appears on the tv telling you the input source and the display settings in this case 1080i/50hz this information only appears usually when u switch to a different input i.e component for the xbox, why does it do this now and again, its very annoying i changed it to 720p and its no different.

hope you can understand what im trying to say, or if anybody has had this fault themselves.

thanks
scott
