I wasnââ‚ ¬Ã¢â€žÂ¢t too sure whether or not he had made the connection properly or used some sub-standard cable so got in touch with CS who in-turn got another guy to come out a few days later. He in turn said he had some †˜differentâ ۉâ₠žÂ¢ cable to the one that the previous guy had used and rigged that up, but this time adding one of the small †˜silverÃƒÂ¢à ¢â€šÂ¬Ã¢â€Š¾Ã‚¢ boxes (that the previous guy had taken) at the junction point near the entry point at the wall.. job done again.
I still wasnââ‚ ¬Ã¢â€žÂ¢t happy with the digital picture quality .. so he went away and brought in one of those boxes to test the signal; said he would †˜boostâà ¢â€šÂ¬Ã¢â€ŠÂ¢ it some more but it wasnââ‚ ¬Ã¢â€žÂ¢t really necessary as the levels came up as GREEN (acceptable).. he also added some kind of †˜widgetÃƒÂ¢à ¢â€šÂ¬Ã¢â€Š¾Ã‚¢ prior to the IN point of the NTL box, said there was nothing else that could be done and left.
X amount of weeks later I am still not that happy with the quality of the picture being received; its not as good as it used to be, but as this is relative to the customer its impossible to convey what it was like originally.
Any ideas.. ?

Ok
The cable that feeds the Set top box will not effect the picture quality as such. Thats the thing about a digital picture, if the signal is good the picture will be fine. If the signal is poor then you will either
A) Experience viewing problems pixelation/freezing of the picture and other problems
B) The STB wont work at all
The actual quality of the picture is not affected in the same way an analogue picture is (grainy, etc)
The only exception to what i have described above is IF you are watching the DIGITAL picture through an RF fly lead (that is a coax cable to your TV instead of a scart).
If you do have an RF fly lead i would have thought it hasnt been changed and would be surprised if this was the problem.
I bet (most respectfully) that you are simply scutinising the picture more since having the work done.
