havent played with edl... but bits and pieces of the transcoding 
features that are to come in myth 0.11 are aldready present... the 
'mythtranscode' script for example... you can specify something like this:

$ mythtranscode -l -k -p Transcode -s 2003-07-12-19:00:00 -c 1056

just make sure that the recording settings in the Transcode profile are 
as you want them (or identical to your source recording settings if you 
dont care, since your converting it to svcd anyway)

do a 'mythtranscode --help' for details on what those command line 
options are... that script will output the same file it used as source 
(in my case "1056_20030712190000_20030712193000.nuv") but a new file 
will be there with the same name but ending in .nuv.tmp that wont 
contain the commercials. then you can use the same encoding process you 
have been using for converting .nuvs to svcd.

i know that isnt the answer you were looking for but the results should 
be the results that you desire (svcd's with the commercials removed 
according to mythtv's cutlist).  or you could just wait for these 
transcoding features to be fully implemented into myth... which judging 
by the flurry of activity in the dev and commits list probably isnt that 
far off.

hope this helps. if you get it down to a science then maybe you could 
write a nice little script for all of us to use? ;-)
