It must be a digisender. They are ok but you will experience a loss in picture quality. Perhaps this will be less pronounced as the DVD player is in the same room as the LCD, so there will be little if no obstruction.
However, as you have just bought a new LCD at considerable expense, do you not want to experience superior picture quality?
My advice: ditch the idea of a digisender (you refer to it as a wireless scart) and position the DVD player in close proximity to your new TV. Hook it up with a good quality cable, sit back and enjoy!
