A while ago I saw a TAP which prevented the TV from auto changing to the topfield when it started for a recording, so if watching a DVD etc then it wouldn't switch to the PVR. I didn't need it then but now I do as it's been switching in the middle of PS3 games! 
I have tried searching but can't find it now
. I'm pretty sure it was a TAP so just wondered if anyone here knows what it's called/where to get it
Thanks
