I have a NTL digital box connected to DVR (L1)via scart. When recording on the hard disc on terrestial channels, in order to watch NTL whilst recording is in progress I can activate 'scart through' via +button on DVR facia. I can then access the NTL signal. However I noticed last night this feature does not work whilst recording terrestial Channel 5 via DVD disc and attempting to watch football on NTL. I hurriedly had to cancel DVD recording to HDD before I could operate 'scart through'. Is this normal or am I again doing something stupid? Is there also a way to do this via remote control? Cheers.
