I bought an Amstrad CPC 464 recently and it came with the CTM 644 monitor. Works great with the Amstrad CPC as you'd expect and I recently received a Scart adapter to allow me to connect up my ZX Spectrum, which also works great.

Now being that the adapter is supposed to be generally compatible with all RGB Scart input devices, I thought about testing out an old DVD Recorder, with the thinking being that as the DVD Recorder can accept Composite, SVideo & RGB inputs and output them all to RGB, it might be a good way of getting other devices that aren't natively RGB capable, connected to this monitor.

Unfortunately, it doesn't seem to work right, with horizontal distortion as in the pics below and I was wondering if anybody can suggest what may be the cause and any possible solutions?

Note: The images appear to show a vertical alignment issue re-the black bars, which I'm not bothered about, as I don't intend to play movies on this thing. The alignment of the DVD Recorder's system menus & other input images are correct, it's just the horizontal distortion that is really the issue.
