ive set the 500 hd up by connecting to tv using a scart , but have now got a hd tv , do i just connect to tv using hdmi lead or do i have to go into menu of 500hd and change some settings to get picture on tv ? also is it ok to connect 500hd to dvd recorder using scart whilst also having it connected to tv with hdmi, so i can record from 500 . thanks
