hi, joboehl,

that is my problem !!!
But I think, in a house with one person, it is a feature, but in a family with 2 or more persons (and clients) it is a confusion.

The WAF is very bad :sorry:

My wife looks an excitingly tv-movie and now I switch to this channel, its ok. But if I switch then to another channel, I get many trouble :-(

    The concept behind this is: If you subscribe to a channel someone else is in control, you must known that you are subject to what the other person is doing.

    Like a said before there are basically 2 options here. When the owner changes channel you can either affect the subscribers (turn off tv, change channel with the owner) or affect the owner (ie: prohibits the channel change if no other card is available to tune). There are no other options.

    Sharing a TV Tuner has it's implications and limitations. As of today (haven't tested), what should happen is that if your wife subscribed to what you are watching and you change the channel on a DVB card, and no other card is available to tune, the TV on your wife computer should be turned off. AFAIK, that's the design now. Can you confirm this is how it happens to you?

    I understand, joboehl. It seems, that the devs have only two solutions (master-slave or tv out) by this design.:D
    But both solutions are not good and will caused many probs.

    As I said, tuner sharing will always have implications and limitations.

    What's your suggestion? Prohibit the owner to change the channel?

    I already predicted issues and discussions about this feature
    since it was first raised as a feature request somewhere in the half of 2006

    The problem we have here is:
    - we have 1 tv card
    - we have 2 (or more) users
    - each user wants to watch any tv channel he/she likes
    - each user wants to record any tv channel he/she likes

    As you can see this is simply not possible and the requirements are conflicting.
    There is no perfect solution other then to buy and install a 2nd and 3th tv card.
    So what we have done now is implement a solution which we think should work well in most cases. However as said, it aint perfect and it never will be.

    In the current algorithm
    For DVB cards:

    The first user
    - 'owns' the card
    - can zap to other channels within the same transponder
    - can zap to other transponders

    The other users can
    - does NOT own the card
    - watch the stream of user #1
    - zap to other channels within the same transponder
    - cannot zap to other transponders

    for Analog cards:
    The first user
    - owns the card
    - can zap to other channels

    The other users
    - can watch the stream of user #1
    - cannot do anything else

    If you show us a better solution, we can look at implementing that one.
    But each solution has its advantages and drawbacks

    doesnt matter
    with 2 tvcards and 3 or more users we have the same issues as described above

    One more note about the current algorithm in case you have 2 or more tvcards:
    Suppose:
    - user #1 is watching Channel A on card 1 (and is the owner of the card)
    - user #2 is also watching Channel A on card 1

    Now user #1 (the owner) zaps to channel X which is on another transponder
    what happens?

    If you have a 2nd tvcard which is idle then:
    - user#1 is transferred to card#2 which then watches channel X
    - user#2 stays on card #1 watching channel A and becomes the owner of card #1

    if you only have 1 card, or if the 2nd card is not idle:
    - user#1 is zaps to channel X on card #1
    - user#2 also zaps to channel X on card #1
