Toshiba BDX3100 - Disc Issues

[Dombo1981]

Hi All,

i have had this player a number of years and i bought it region free, has played anything i throw at it from around the world,
i recently got the Friday 13th Box set from scream factoy and i am having awful trouble playing them, i will get unknown disc error maybe 10 or 20 times but then it will suddenly play, everything plays as it should apart from this set, but i have read somewhere some players have issues with scream factory discs? can anyone shed any light on this or if they have ever had this issue with the player.
Thanks for your help
Dom
