Please describe the problem:
I have come across a problem while trying to play a DVD using gst-launch.

Steps to reproduce:
1.  gst-launch dvdreadsrc title=1 ! dvddemux name=dvd dvd. ! mpeg2dec ! queue !
ffmpegcolorspace ! xvimagesink dvd. ! a52dec ! queue ! audioconvert !
audioresample ! alsasink

This pipeline causes a blank, black window to appear.  Neither audio nor video
is played.  Running top shows that gst-launch is using very few CPU cycles.

2.  gst-launch dvdreadsrc title=1 ! dvddemux name=dvd dvd. ! mpeg2dec ! queue !
ffmpegcolorspace ! xvimagesink dvd. ! fakesink

I ran the above pipeline to try and isolate the problem.  The audio stream is
simply going into a fakesink, but the symptoms are the same as pipeline 1.

3.  gst-launch dvdreadsrc title=1 ! dvddemux name=dvd dvd. ! mpeg2dec ! queue !
ffmpegcolorspace ! xvimagesink

This pipeline plays the DVD video fine.  However, audio is not played because
the pipeline does not specify anything for audio.

4.  gst-launch filesrc location=/mnt/cdrom/video_ts/vts_01_0.vob ! dvddemux
name=dvd dvd. ! mpeg2dec ! queue ! ffmpegcolorspace ! xvimagesink dvd. ! a52dec
! queue ! audioconvert ! audioresample ! alsasink

Again trying to isolate the problem.  This pipeline plays both audio and video.
 However, the output is jumbled because of CSS.

5.  gst-launch dvdreadsrc title=1 ! decodebin name=dvd dvd. ! queue !
ffmpegcolorspace ! xvimagesink dvd. ! audioconvert ! queue ! alsasink

This pipeline plays audio and video.  However, the performance is not very good
(see bug #339233, which prompted me to try the other pipelines.)

Does this happen every time?


Other information:
The test system is a PowerPC G3 iBook running Fedore Core 5.
