120 min discs and will they work? I use Convertxtodvd version 4 and i've been burning some movies lately and some work some dont, i wonder if it's because some of them are longer than 120 mins and i've been burning them to DVD+R 4.7 gb 8x 120 mins discs. Is this why there not working? I've burned other movies under 2 hours and they've worked just fine. Please I need help!!
