I am not the expert here for this type of thing - but I think most if not all ATSC is mpeg2 (some satellite feeds are more compressed). So, I don't think it's the format, I think it's the amount of data that the MediaMVP box can not handle. If true, and if the MythTV back end would screen for the bit rates of different files, then, maybe, MythTV could transcode to a lower bit rate or there may be a creative way to tell the client to pull the file using VLC - which could do the transcoding. Just thinking out loud... anyone know different? ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
