Please describe the problem:
after speaking with ddennedy, about libdv printing out error to stderr
by default, he suggested to add dv_set_error_log (dv_decoder_t *dv, NULL);
in the gst plugin to make dv capture as usable as possible.
here is a link to the upstream bugtracker:

Steps to reproduce:

j^: Can you make sure that that symbol is available? I.e. figure out at what version libdv started having that symbol, and then either require that version or (better) add an ifdef to run that line only if the version is new enough.

Also add a Changelog entry in your patch please :)

p.s. edit your bugzilla profile to put your real name :-)

looking at the changelog in libdv this was 
introduced in version 0.98 (released 2002-07-30).

not sure if checking is needed at all.
