I have just got a new DVD player, a Sony DVP-SR750H.  I want to connect it to my TV which is a Sony Bravia KDL-32V4000.

However, whilst on the DVD player there is a designated red hole, yellow hole and white hole, on my TV there are 2 red holes, a white hole, a blue hole and a green hole.

Therefore I don't know which holes to stick the red, yellow and white things into!  Tried various combinations and get a lot of buzzing. 

There are also matching holes on the side which have the right colour combinations, but this also gives a lot of buzzing.

So:  which thing do I stick in which hole?

Also, if this can't be done and I need to buy an HDMI connecting cable, how on earth am I supposed to know from the millions out there on the market, which to go for?  It only needs to be about 3/4 of a metre long, too.
