IFS is a official interface (-> man bash) ... why not using it?

I do not understand your question.  I've only test this on the
shell prompt and have done a cut&past into the mail.  Nevertheless
the IFS interface has to work also in scripts or the shell
program is buggy.

The test above could be simple put into a script:
-------------------------% cut %-------------------------------------
#!/bin/sh -x

VDRPRG="echo"
VDRCMD="$VDRPRG:-Pmp3 -m /video/plugins/mount.sh"
VDRCMD="$VDRCMD:-Pmplayer -m /video/plugins/mount.sh \
        -M /video/plugins/mplayer.sh"

OIFS="$IFS"
IFS=:
$VDRCMD
IFS="$OIFS"
-------------------------% cut %-------------------------------------

now add you code, replace `echo' with `vdr', and remove `-x'.
