multiple bt8x8 cards on single system?

[qilu]

Hello all,

Has anybody got multiple bt8x8 cards capturing video simultaneously on a single system? I need to be able to switch the video input signal on each card.

Usind WDM driver provided at SourceForge:
1. Have a separate SYS file for each card (for example bt8x8_1.sys, bt8x8_2.sys...).
2. Create a separate INF file for each card, where the correct sys file would be specified.
3. Install cards one-by-one, providing the correct INF file.

...Or you can use DScaler program from http://sourceforge.net/projects/deinterlace/.
The last version of this program supports multiple BT8X8 based cards.

I tried adding a separate sys file for 2 cards,
and changing for example all references to
bt848.sys to bt848b.sys

This didn't work - error on installation.

I then tried changing any reference to bt848 to bt848b
as well as changing the strings identifying the different
devices. Would someone have a diff between two
inf files to show how this needs to be done?

Thanks,
Bill

Okay, it's actually fairly trivial -
create several directories and
copy in bt848.inf & bt848.sys.

In the .inf files, just change the
identification strings:

BT848.VideoDeviceDesc=  "Conexant's BtPCI WDM Video Capture"
BT848.AudioDeviceDesc=  "Conexant's BtPCI WDM Audio Capture"
BT848.Capture=          "Conexant's BtPCI Capture"
BT848.TvAudio=          "Conexant's BtPCI Tv Audio"
BT848.Crossbar=            "Conexant's BtPCI Crossbar"
BT848.Tuner=            "Conexant's BtPCI Tv Tuner"

to be Capture 2, Tuner 2, Crossbar 2, etc.
