[mythtv-users] MythDVD rip & transcode

Hi,

    I just decided to try using the MythDVD.  I ripped a couple 16:9
anamorphic movies with DVD rip.  I selected the Excellent option for
the rip, and I have the option to use xvid enabled.  I'm using
0.20-fixes on Fedora Core 4.

    The resultant file has black bars added to the top and bottom.
When I play it on mythvideo on my HDTV it does not fill the screen but
rather has a black border on all four sides.  The width is larger than
the 4:3 area of my TV though, so I'm not quite sure what ratio the
file is in.

Here is the log from mtd regarding transcode.
17:35:35: launching job: job dvd 1 1 2 1 -1 /var/storage/shows/DEVIL_PRADA_WS
17:35:35: transcode command will be: transcode -i
/var/lib/mythdvd/temp/DEVIL_PRADA_WS/vob/ -g 720x480 -f 0,1 -M 2 -V -y
xvid,null -A -N 0x2000 -o /dev/null --print_status 20 --
color 0 -R 1,twopass.log
17:35:35: job thread beginning to rip dvd title
17:41:20: a client socket has been closed
17:45:25: a client socket has been opened
17:51:09: job thread finished ripping dvd title
18:04:36: a client socket has been closed
18:05:07: DVD removed
18:59:46: transcode command will be: transcode -i
/var/lib/mythdvd/temp/DEVIL_PRADA_WS/vob/ -g 720x480 -f 0,1 -M 2 -V -y
xvid -A -N 0x2000 -o /var/storage/shows/DEVIL_PRADA_WS.a
vi --print_status 20 --color 0 -R 2,twopass.log


The resulting file looks pretty good, sounds good from the little bit
I watched, it just seems that the aspect ratio of the resulting file
isn't quite right.

I did find this on the Wiki at
http://www.mythtv.org/wiki/index.php/User_Manual:Daily_Use
Options available are dependant on the DVD inserted

    * Perfect : Available for all Discs. Makes an exact copy of the MPEG file
    * Excellent : 4:3 and 16:9 non-letterboxed Only. Transcode the
MPEG file at a high bitrate. Resultant files size is approx 2GB
    * Good : All Other . Transcode the MPEG file at average bitrate.
Resultant file size is approx 800MB

I'm pretty sure that non-letterboxed is the "enhanced for widescreen
tv" or "anamorphic" style of movie, but I may have that backwards.
I'll try good on a movie and see how it turns out.

Thanks in advance.
 Billy
