Thanks again to you all for your input.
Alanmelon - I have now swapped the outputs from my STB, so that the scart from the VCR socket (on the STB) goes to the TV. My TV clearly signals this as a CVBS (composite video) signal.
The scart output on the STB marked TV now goes to the E55, and on to the TV. Success! I can now record to DVD using an RGB signal
Perhaps I am asking too much here, but I would still like a definitive answer to the question about whether the Pace Di4000-N is designed to give an RGB output from both scarts. Why? Because I quite often like to be watching a DVD, and use the dual-screen or PiP function of the TV to monitor the NTL TV signal. An example might be watching a DVD of last night's football, while seeing if they have kicked off at tonight's game yet (or my wife might want to watch the lottery results live while I keep watching the footie on DVD).
If I see that I want to watch the NTL broadcast, I was hoping to pause the DVD, switch to the scart that goes direct from STB to TV, and keep watching - but at the moment, that picture will only be composite
Perhaps I am wanting too much from NTL.
Of course, none of this was an issue with my cheap supermarket TV and VCR, but after spending £900 for the TV and £220 for the DVD-R, I would like to be able to use them to their full capability.
Just to recap, for anyone else with the same kit who has similar problems, I now have
STB --> TV (composite via TV out from STB)
STB --> E55 --> TV (RGB via VCR out from STB)
VCR --> TV
The AV2/Ext2 setting for the Panasonic DMRE55 is as follows -
Input- RGB
Connection - Decoder (but Normal works equally well)
Ext Link - Ext Link 1 (but Ext Link 2 works equally well)
Tristan - I see your logic, and it makes perfect sense .... but are you speculating, or speaking from certain knowledge? I simply don't know whether the STB should be sending RGB from both scarts, or was designed to send RGB via the VCR, and RGB via the TV. If it is designed to do this, do NTL supply a different model that outputs RGB on both?
If you are right (I have no reason do doubt you, as I don't know the first thing about STBs), I can see this becoming more of an issue as multi-scart TVs and DVD-Rs become more widespread. For instance, I presume I could split the single RGB out from the STB to two separate scarts on the TV (2 of the 4 TV scarts are RGB-enabled) - but one of the reasons for buying this TV was because the number of scarts should reduce or eliminate the need for splitters, with the cost and problems that they can bring.
Thanks once more to you all for your thoughts, suggestions, opinions and most of all, your time.
