Movies wont play on my dvd player

Hi everyone. I need some advice please. When i burn movies to disk that i’ve downloaded i CAN play the burnt DVD’s on my laptop but i CAN’T play them on my DVD player (the DVD player say “no disk”). Im using “ConvertXtoDVD” to convert and burn the downloaded file and i’m also using “K-lite Mega Codec Pack”. What do i need to do so i can play the BURNT DVD’s on BOTH my laptop and my DVD player???

Speaking generally on burnt DVD’s not playing in dvd players: You may want to look into “book type” or “bitsetting”. And try other dvd players to see if they work in any others.
