Flickering on hdtv using nero burning software

hi all

Got probs and need some expert advice
just purchased a hdtv and when i play my dvds on this set the picture flickers, but when played on a regular tv the pictures fine.
Im using nero express to burn, but tried nerovision and changed the burning settings to 16:9 ratio (as ive been told this is where the prob is) but then the data is over 4.3gb and wont fit on a single sided dvd??
how do i overcome this prob??

thanks for any replies

Deano :doh:

Try using DVD Shrink, a free sofware, it will compress the files to fit a single layer DVD.
