DvCamera versus AVDV Converter

[Davees Software]

Have a Cannon SR70 hooked up and a Canopus AVDC 100 (converter). Using the
IamExtDevice, the converter responds just like it is a vcr_type, recording,
stepping, timecode reading, etc, etc, etc.

Attempting to do Scene Detecting (during capture)via the timecode reader.
Mastered using the DvCamera but since the converter responds like it's a
DvCamera when you try to do scene detecting the capture comes to a stand
still.

Yes, the GetTimeCode does fail on the converter but what I want to do is
detect that it is NOT actually a DvCamera. I have discovered that when you
activate the ExtTransport against the converter and do a put_mode with
anything but play, stop or freeze that it does fail.

When initializing the filter for the DvDevice I go ahead and grab the
ExtDevice and althought the DvDevice is stopped if I issued a
put_mode(ED_MODE_STEP_REV) that the true DvCamera will return 80070047 while
the converter will return 80070032. This is the only way which I can detect
converter or real camera. Works fine against the 2 devices I have but will
it work against other converters and camera.

Does anyone know how to actually tell 100% of the time
