Question about converting .avi to .iso and burning.?

i have downloaded movies already in iso format and are always average 4.5gb in size. when i use power iso to burn them they come out fine and play perfect on my dvd player. now i downloaded a movie in .avi and used powerISO to convert it to an .iso and after i burned it and put it in my dvd player it gets an error message. how can i convert my .avi to iso and them work when i try and watch them on my dvd player…. o and i tried burning .avi with nero but it takes between 4-7 hours to burn 700mb (when power iso takes an hour to burn 4.5gb) and also the movie messes up after 30 minutes or so when watching…..thanks

You can either install both and dvdflick will pass straight to imgburn (process is seamless) to make the dvd, or get dvdflick to output to iso and use your iso software to burn (two step process)

The reason it wont play on your dvd is because the machine wont play avis (thats my guess but hard to say for sure without more info).. dvdflick will convert to mpeg2 so it will play on any stand-alone dvd player.
