try convertxtodvd or if you got the money get Cinema Craft Encoder as it has a far better quality then convertxtodvd and winavi video converter but its alot more confusing heres the guide i use for CCEhttp://forum.videohelp.com/viewtopic.php?t=222898
Keep in mind that garbage in = garbage out , so you won't a great quality from those movie formats (usually they are for making small clips, they wuill never reach the quality of a DivXAVI).
An 'idiot application' is TMPGEnc. Encoding DVD CBR ddoesn't take much time.
You just have to
1) fint the 'optimal' butrate putting the movie's length (or the movies' length, if you want to put more movies on a DVD) into a bitrate calculator (like DVTool). For audio , set 128 kbps (MP3 CD quality), which is among the average bitrate you find, in those movies.
2) use old TMPGEnc Plus to make M2V + WAV from the movie. Start the wizard and choose DVD (your system), then press the [settings] button.
3) Encode the movie into a CBR DVD with a bitrate = DVTool result, and keep motion search precision = highest quality; video arrange method = full screen (keep aspect ratio). Once you've made one project, save it and re-use it, loading another movie anc changing only the bitrate.
4) convert the WAV --> AC3 128 kbps with FFMPEG GUI
5) author M2V+AC3 ==> DVD with any application you want (DVD Lab, IFOEdit which is also free, ...)
TMPGenc Plus is a user friendly application, produces nice quality movies, owns the licence to convert WMV movies and also can change movies from a TV system to another (PAL <--> NTSC; please note: CCE doesn't). It is only slow to encode VBR DVD (CCE is faster), but if you encode a CBR DVD you'll need few hours. Again, garbage in = garbage out , so preparing a VBR DVD isn't necessary.
