Apparantely Panasonic TH-50PHD6EX is sold in Germany/Sweden etc, while TH-50PHD6BX is sold in the UK and TH-50PHD6UY in the USA. Now, what is the difference between them? I think the UY version ships with an S-Video/composite video board (and is hell of a lot cheaper), but are there any other differences? What differs the BX version from the EX version? Does anyone know?
