I got a Sony DVDRW with nero 7 essentials. For some reason, Nero will play my DVD's but will not play audio. It claims it needs DVD-Video multichannel plug-in. Huh? I plan to use my DVD burner to burn DVD's I DL from torrents in AVI form, averaging about 700 mb. I also plan to make edited discs of home movies I have recorded. (VLC player plays video and audio, but it is choppy, so it looks like I will have to purchase Nero.) If my Nero essentials has a 30 day trial, shouldn't I at least be able to watch a DVD or burn some things to decide if I like it or not? Which Nero should I purchase, i.e., which is cheapest that will allow me to do the things I have described?
