I feel like I really missed something somewhere...

Question

So I was watching Family Guy last night using Xine (I like menus), and I noticed that the quality was really bad, so I cranked up the deinterlacing, and once my CPU topped 100%, the quality was "acceptable". 
But then I was cooking, so the menus annoyed me (it doesn't have a play all button), so I used mplayer with this command: "for i in `seq 2 9`; do mplayer dvd://${i} -dvd-device /dev/hdc -vo xv; done", and the picture quality was perfect (note the lack of any deinterlace filters).
So I wondered why Xine was giving me such crap quality, and I noticed that "Video Device" was set to "Auto" (which I always thought meant it picked xv over all of the others), but I changed it to "xv", and now I get the same quality as mplayer without any deinterlacing.
Now, I swear a few years ago when I was fiddling with that kinda thing, I had to use deinterlacers with "xv" to get the same quality as I get now (using just xv alone).  So, does xv now use my graphics cards onboard MPEG-2 decoding, or does xv have it's own deinterlacer, or does something else happen?  I really feel like I missed something somewhere...

1. Triple-click the line below to select it:
~/.Trash
2. Right-click or control-click the highlighted line and select
Services ▹ Show Info

3. The dialog should show "You can read and write" in the Sharing & Permissions section. If that's not what it shows, click the padlock icon in the lower right corner of the window and enter your password when prompted. Use the plus- and minus-sign buttons to give yourself Read & Write access and "everyone" No Access. Delete any other entries in the access list.
4. In the General section, uncheck the box marked Locked if it's checked.
5. From the action menu (gear icon) at the bottom of the dialog, select Apply to enclosed items and confirm.
6. Close the Info window and test.
*If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). Open a TextEdit window and paste into it (command-V). Select the line you just pasted and continue as above.
