problems burning .mpg files with toast 6 to SVCD format

[spigfry]

MAC OSX 10.3.9 / Toast Titanium v.6 / ffmpegX 0.0.9u

newbie mac burning question

Hi I have a bunch of .mpg files that I'm trying to put onto one CD using toast 6 - I dropped the mpg onto ffmpegX to see what type it was and it shows as

mpeg-2 480x576, 2350kbps, 25fps

audio mp2,44100hz 192 kpbs

First Q: is there a utility such as Gspot but for the Mac that performs a similar function in identyfying codecs etc? or is ffmepgx the best way to identify frame rates / codecs etc

Second - when I select info from ffmpegX it says "alert" and nothing else?

I then tried dropping the mpgs into Toast 6 to create a DVD - I have the options video - pal - and the quality changed to svcd to allow me to squeeze more episodes onto a DVD - i am recording onto a standard DVD-R

When I try to record Toast gives me the message

CDROM XA or Audio tracks cannot be written to DVD

same problem if i choose VCD instead of SVCD

Any ideas as to the quickest way to resolve this? do I need to run it through ffmpegX to change the audio in some way, or is it something simple I'm overlooking??
Or is there a way to change a bunch of .mpg files into one VIDEO_TS folder I can then give to Toast?

I checked all the guides but nothing seems obvious, apologies if I overlooked something.

Thx in advance

Well, several points:
1. Audio for dvd should be 48000Hz
2. Horisontal resolution for dvd should be 720 or 704 or 352
3. The multiplexing for dvd is different than for svcd
So at least you need an authoring programm for mac - dvdauthor for example.
