    check the documents about DCF, with it you can basically disable files untill users have downloaded right keys for them.

    firstly you need to remember that thigs work differently between different devices. DCF for example doesn't work untill OS 8. With OS 9 also some functionalities with some phones are not working correctly, like with 3250 DCF with Videoa & SIS files are not working as they should.

    Anyway, have a look into DRMCommon and Helper API's, you could use them to check if the content has keys alreay, and if not you could use them to retrieve keys.

    Thank very much yucca.

    However, From the above quote . Do you mean that DCF file with video not support in 3250 ? I don't have real device to test.
    But my job now is doing with dcf video file.

    What's problem in 3250 and another os 9.0 devices ?

    I think it is propably firmware versio related problem, and in never ones it might work correctly already. Anyway, you could try finding a post written by nitin, he suggested using RFile while opening it, and he said that with that workaround DCF should also work with video files on 3250, though never got time to check that out yet.
