Data Dvd problem

[casio1]

I recently burned a data dvd with about 1,200 mpeg2 files on it, I usually do this with cd-r's so i can review the footage and write up a clip log away from the pc on a standalone player. But that was usually with only 300 clips each, so to save more cd-r's I did the data dvd. But when I play it on a dvd player it only shows me 645 files.
All those play fine, and I confirmed the mpegs are on the disk, but the player doesn't recognise this can anyone help?

Player limitation as to the number of files it can process/read into it's menu buffer ? I'd check the player manual.
