Original XBOX - Some games look perfect, others Blurry/"ghosting"

[Misanthropy83]

Hello.

I have a modded crystal PAL xbox (Xecuter2) running on a Sony Trinitron CRT TV, using a standard scart cable. Some games look beautiful and sharp, like San Andreas for example (the modded one from this very site). Other games have terrible "ghosting" graphics, I've tried using different region and aspect ratio settings in both the Evo dash and the MS one, but it makes no difference. I realise scart cables don't give the best quality, but as stated, some games look fine. In addition, the same TV is connected to a Gamecube, Dreamcast, 360 and PS2 (the ps2 is using S-video) and they look glorious (for their time )
I'm running most games from the internal HDD and have also tried adjusting the settings on the TV.

Any help on this would be kindly welcomed.

You have not mentioned any games that run badly just the ones that run good...
