Hi, I’ve installed Imgburn v1.3 and I’ve seen that it can control smart-burn features of the writers (for benq, lite-on and plextor) but unfortunately imgburn doesnt support all file types like avi files etc… it supports .img, .dvd, .iso etc… But I have lots of .avi files to write so is there any other software that can control smart-burn like imgburn?? 
Not that I have seen.
You want fast (good quality) avi to DVD look into WinAVI 7.5
If you have lots of avi, the cheaper solution is to buy a standalone able to play avi files. Nowdays there are cheap players able to read almost anything 
cdburnerxp might do. smartburn is enabled by default.
