File naming for auto detection ??

[Mike-UK]

is there and special way to name files so my collection can index them properly , ive just added a new Tv series to my dune files are in a folder names with the show and the files named S01E01 and up, dune sees the show and makes a corrdct entry into my collection, but it only recognises a few episodes and leaves some out even though the naming is the same format ?,
