    Cool, quoting my own message ;)
    Just got notified on the dvbschop24 forum that a new version of the driver is available. This version is a response to the 'cannot build graph' message I posted, so.......
    bugger, I am still at work so I cannot test right away....

    Anyway, the new version can be found here: dvbshop24.com - The network for PC-TV! - Windows 7 BETA Driver Connect incl. CI f. MCE - Forum and Support dvbshop24.com

    please report back here, I know i will ;)
    regards,
    Ruud.

    with this new 1.0.4.3 driver, still the same issue (on the surface anyway) then with the new 1.0.4.2 driver although there is a reaction of a win7 MCE user that this version rocks: fast channel switching, no more timing issues on the ci en no more BSOD's..... *** I want that to for MP :p ***

    Posted my log over at the dvbshop24 forum.....dvbshop24.com - The network for PC-TV! - TT CT3650 CI and MediaPortal - Forum and Support dvbshop24.com

    regards,
    Ruud.

    Okay,

    just as an update, got a reply over at the DVB forum: dvbshop24.com - The network for PC-TV! - TT CT3650 CI and MediaPortal - Forum and Support dvbshop24.com

    Here's there answer:
    and here's my reply:
    This does however shed some light on why decryption is not working and what the MCE version does...
    I hope that I have asked the correct questions, otherwise feel free to jump in ;)
    regards,
    Ruud.

    @Riksmith and Morpheus_xx,

    What I read here and how I interpret it is that they (TT) cannot change how MCE interacts with regards to descrambling so they handle the decrypting in the driver. This as how MediaPortal handles it now: in the TV Server.

    So this could be a good change for us.... if we can make use of the new MCE driver, then decrypting would be less complicated in TV Server because this is then handled in the driver.... from a TV Server perspective it is all 'FTA'....

    Is this correct?
    Can you eleborate from a technical point of view?
    What would be the impact of this for TV Server functionality?

    thanks in advance,
    regards,
    Ruud.

    the current implementation is following:

    we use the TT supplied API to:
    a) detect / open device
    b) send the current PMT to CAM to start descrambling
    c) attach to CI menu callbacks and actions.

    while I implemented the CAM support for DigitalDevices, their drivers where also automatically decrypting the service, which was set inside the tune request. So probably the TT MCE driver are doing sth. similiar: starting to descramble the single service you tune to.

    OR they implemented some of the IBDA_ interfaces vor CAM support, but I never seen such before.

    This means:
    if TT can provide us a way how the "auto-descrambling" should work, we could try to adopt this behaviour. BUT at least we would loose CI menu cupport and probably are limited to 1 simultanous service decoding.

    You're welcome :)
    If you are asked by the support to test something or give them some info and you need a hand, do not hesitate to ask. If I'm at home and have a few minutes (depends on the kids...), I would be glad to help!
