i just authored my first rmvb to dvd using WinAvi and the DVD plays back fine but the video isnt what i hoped it to be. i followed afonics guide to making it which was having the bitrate to 224, NTSC and 16:9. for those who have used WinAvi to convert RMVB to DVD was AUTO the best aspect ratio to use? since i used 16:9 the picture is kinda wide. and any other changes to make before i reauthor this dvd which takes about 3 hrs?

btw is there a rule of thumb to go by when converting rmvb to dvd? i did 10 rmvb's and it ended up not fitting, had to take one out. any way to know in advance such as TMPGENC's DVD Author when draggin a MPGs to author into dvd.

thanks in advance
