Question: Anyone knows some good video conversion software I can use for my Mac? I need something that will convert AVI files to DVD so I can watch them on my DVD player. Right now I am using iDVD which is working but the quality of the picture doesn't seem so good.
Answer: You have to understand that the DVD quality may be lower than the original .avi because the video file get compressed in MPEG2 (the DVD format), on iDVD you can easily change the quality settings, but if the video is too long you may not achieve a reasonable bit rate (number of bit per seconds used to compress the video, higher means better quality).
To get higher quality you may use a Double Layer DVD (if your Mac has a DL super drive) or you can split the video into two parts.
Software that may help you a lot on video conversions is AVI to DVD Converter for Mac, which can easily convert AVI files to DVD on Mac without losing quality.
