guides=scroll to top of page 3rd in from left,use dvdfab if you get errors with shrink then run it thru shrink afterwards if you want to trim front & end frames,otherwise may as well use dvdfab then burn with fab,check settings of fab top right corner of program,set custom size of 4480,for the time being use rewritable dvd's to save making coasters,you'll also need decent quality media in the past TDK are fine however i've now switched to verbatim with AZO on packaging

You can also burn at slower speeds to help prevent making coasters.
