 I recently transcoded some of my recordings to XviD and X.264 in an AVI
 container.  The previews generated by MythWeb (via the UPnP
 /Myth/GetPreviewImage method) are always garbled.  It looks as though the
 frames that are grabbed are not keyframes, but rather something in
 between.  The result is a bad image.  I was sure to rebuild the seektable
 prior to generating the preview pixmaps.

 This only seems to happen for the AVI container.  NuppleVideo and MPEG-2
 work fine.  I have not tested other container formats.

 I have attached sample .png files to illustrate the results.
