And I believe you!   It's why I did what I did -- I just got two
HD tuner boxes from RCN purely to plug in via FireWire!

* grumbles *

I bought this card because in a previous email you said that all TI
cards were supported!   *sighs*

But yes!  I'll happily trade you!  I'm in town this week, so tomorrow or
Saturday I could swap out with you.  I'm in Somerville.  When's a good
time?

I've got only Friday and Saturday before I fly away again, so I'd really
like to get /something/ working before I go..   If it's with this
card, great.  If it's a swap-out, that works, too!  Either way.
