isochronous receives?

Keith, et. al,

I am having problems with isochronous receives, and remembered just as
I was getting ready to dig into the source that there was a message
about this stuff. Lo and behold your message to linux1394-user from
September 7:

I'm trying to receive isochronous streams (using libraw1394 1.2.0), and
I've noticed that if data is transmitted on channel 63, then my app tends
to work fine. If the stream is on a different channel, then I don't see
any isochronous packets at all. I'm using 2.4.29, I've also tried 2.6.15
with similar results, can't seem to receive channels < 63.

Did you ultimately have any success getting this going? Funnily
enough, when I tested isochronous stuff in July, I just did iso
transmit since I figured receives *must* be working since everyone has
camcorders and whatnot. My currently my iso xmit stuff does appear to
be working, but iso receives are not.

I have a Firespy and no reason not to trust it, so I can see the junk
I'm spewing out. I've tried transmitting on channels 4 and 63 (per
your advice), but neither works for me. I suppose it could my
stuff... nah.
