newbie converting asf/wmv to dvd ready mpeg questions

[chooklotto]

ok i have a number of wmv/asf/avi files that i want to convert to dvd ready mpeg.how do i tell if the original clips are in pal or ntsc?
if i want them all to be pal for example how can i convert them wihout sound going out of sync? i have used virtualdub to find out the res etc but i cant see in it if its pal or ntsc. Also the res is 640x480 which doesnt seem to fit the description of what res dvd can be, how can i convert it? im using tmpegenc but if anyone can suggest other freeware/cheap programs to use i will try them too. Is there any program that will do it all in one, convert all types of files then author the dvd with menus?
TIA

couldnt find the dload link for that program only the other ones, anyway im trying Tmpgenc and i seem to be working it out but theres one file that i load into it and it freezes the program up half way thru checking the field order,i have used Videofix on this and its still doing it though, any ideas?

It's the only cheap, one-button, sort of app.
There are others that cost more, look under DVD Authoring in the tools section.
There are also free ones, but more confusing.
There are loads of free apps that will do what you want, but not all in one step.
I suggest you start with the guides, then decide what software you want to use.
Try dvd2svcd (which also does avi to dvd).
Try Ulead 3 (free demo).

Get GSpot to tell if it's PAL or NTSC, and what codecs are used.

Personally, I use GSpot to find out what it is.
Virtualdub to edit.
TMPGEnc or Mainconcept to encode.
TMPGEnc DVD Author or Nerovision Express to author and burn.

reboot, what version of Gspot are you using? I tried 2.2 and 2.21 and cant get any framerate info on WMV/ASF files. I wanted to find the FPS because i want to do some testing with these filetypes in AviSynth, it requires the fps to be passed as argument to the DirectShowSource function. The solution i found was to open the files in WMP and click View - Statistics, then the advaced Tab. Still some of the clips played way too slow when opening the AviSynth script in WMP.

Yup, WMP does as good as anything on wm* and asf files.
Avisynth can only handle (the 3) standard fps of 23.97, 25, and 29.97. If your input video is any other framerate, avisynth chokes, and attempts to "guess" by setting itself to the nearest standard.
I have dozens of avi's at 14.985 fps (half NTSC), and avisynth guesses at 23.97, which makes the resulting mpeg run just a bit fast, and audio sound like the Chipmunks
