AVI file, not centered
Here's what ffmpeg -i has to say about the file:
Input #0, avi, from 's01e01 - The Muppet Show s01ep01.avi':
Duration: 00:26:10.01, start: 0.000000, bitrate: 646 kb/s
Stream #0.0: Video: msmpeg4, yuv420p, 480x320, 23.98 tbr, 23.98 tbn, 23.98 tbc
Stream #0.1: Audio: mp3, 22050 Hz, 2 channels, s16, 47 kb/s
My profile is as follows:
<!-- First remux all h264 video on MPEG-TS stream with ac3 audio transcoding, expected profile AVC_TS_MP_HD_AC3_ISO or AVC_TS_MP_SD_AC3_ISO -->
<Video targetContainer="mpegts" targetACodec="ac3">
<Matches container="avi" vCodec="h264" />
<Matches container="mp4" vCodec="h264" />
<Matches container="matroska" vCodec="h264" />
<!-- if audio different to ac3, must be transcoded -->
<Matches container="mpegts" aCodec="aac" />
<Matches container="mpegts" aCodec="mp3" />
<Matches container="mpegts" aCodec="dca" />
</Video>
<!-- All Others video/audio codec will be transcoded into mpeg2ts, mpeg2video and ac3 audio (MPEG_TS_SD_EU). -->

I suspect this has something to do with the aspect ratio, as mentioned here: viewtopic.php?f=13&t=2055
EDIT: Interestingly, the following file (episode 2), with a slightly different aspect ratio, plays properly centered:
Input #0, avi, from 's01ep02 - The Muppet Show s01ep02.avi':
Duration: 00:26:02.32, start: 0.000000, bitrate: 823 kb/s
Stream #0.0: Video: msmpeg4, yuv420p, 480x360, 25 tbr, 25 tbn, 25 tbc
Stream #0.1: Audio: mp3, 48000 Hz, 1 channels, s16, 64 kb/s
