Chaps i think i may of cracked this problem tho this was over the last 24 hours and the info was found in this forum. I was having problems with the nero and avi speech video problem. I have now successfully burned 3 dvds that work spot on. If you get the programme converttodvd and convert your avi file to dvd format, i then took the video_ts files (nothing in the audio_ts file) and drag and dropped them into nero burn rom nero express then video dvd -video files. Nero then puts these into order and burns to disc and hey presto. The converttodvd takes a while but so far it has worked. Hope this help. I was using bero 188.8.131.52 but cant see while this would work on other versions of nero. Also i am using the new pioneer 112d burner and ritek printable mwdia and burned at 8x speed the disc's max. Good look and may the force be with you!!
