When you have .avi files or Divx files that are too big to go onto one disc you have to split them into two parts.Ive found this software - Virtual dub,which allows me to do so.After splitting the files I can play them on windows media player as two files.The problem is when I go to burn them onto CDR,using nero it will encode the file burn it to disc but when I try to play back the disc there is only sound no picture.Is there anything else I have to do to the file before I burn it to CDR
