    Hello.

    Has anyone gotten this old non-DTV TV video tuner cards to work properly
    in Linux/Debian?

    Thank you in advance. :)

    Thanks. I got the card to be detected, but can't get video to show up
    from my VCR. :(

    The problem with some of these chips, is the chip has multiple inputs,
    and the software must be convinced to look at the correct source. That
    is why there is a "card declaration" in some of the threads you're
    looking at. There are limitations to what Plug and Play can do,
    in terms of configuring the driver for the card.

    The tuners come in various types as well, as do FM radio chips or
    audio solutions. The driver must be told what kind of "helper" hardware
    is on the card, to get some of that stuff to work.

    On one memorable occasion, on a Macintosh, and using a BT878 capture
    card, I had to patch some code with hexedit, changing some bytes which
    controlled the source port. And by doing that, I was able to try
    different inputs until a picture appeared.

    That's all part of the "fun" I guess.

    Getting the card detected, means you're looking at the main chip.
    But it doesn't guarantee you're looking at the right input port,
    configured to control a specific tuner type, and so on. In some card
    designs, there is an EEPROM on an I2C bus, which contains details
    about the tuner and the other hardware. But even with that present,
    you'll still find drivers that want you to enter some "card=xx" type
    parameter. Which makes me wonder whether there are standards or not.

    Ugh. That's nuts. In Windows, it was easy with its PowerVCR II. Bummer.
    :(
