Default install will not play DVDs or MPEG files?

Was rather surprised to find that after install I had no luck playing a DVD or the VOB (mpeg) files off of it, with either Totem or Dragon Player. (This is a DVD that I authored, so no CSS, but does have menu.)
Totem originally asked about some gstreamer plugin (don't recall which) via packagekit (whatever that is). Clicked search but nothing appeared to happen. Went and installed a few additional gstreamer packages that sounded related. Then Totem just sat there with black screen (showing no disc/file info) for DVD or VOB files.
Trying Dragon Player on the DVD, I get a popup window saying:
packagekit-gstreamer-plugin requires additional plugins:
...dvdspu
...rsndvdbin
Clicking on the search button again appears to do nothing whatsoever.
Selecting the VOB file leaves the play button greyed out.
The additional gstreamer packages I installed beyond installer selected ones were:
gstreamer0.10-mpeg-0.10.17-1.mga1
gstreamer0.10-a52dec-0.10.17-1.mga1
gstreamer0.10-resindvd-0.10.21-2.mga1
Since no luck, looked at gstreamer packages installed on Mandriva 2010.2 (which will play DVDs immediately post-install--though jerkily). Only additional one I noticed was plugins-bad, so installed: gstreamer0.10-plugins-bad-0.10.21-2.mga1
This did the trick. Really makes me wonder, though. Is this right that DVDs and mpegs will not play with the default players post install, and that users have to guess about what packages to install, and then they must install plugins that are "not up to par." This is state-of-the-art for Linux video?
