Could somebody here with the new device please open it up and confirm the 
existence of this part?

Yes, I'm positive.  In fact after extracting it I compared it against the 
three other variants of this firmware floating around and it didn't match 
any of them.  The first 8 bytes or so are similar in all cases but that's 
about it.  And this firmware *does* work.  I'll e-mail it to you.

Well possibly.  But since I don't have a PVR150 to compare with I can't be 
sure.  Also we're limited here by what the FX2 controller will perform on 
behalf of the host.  We had discussed before the possibility of getting 
VBI working and I had noted at the time that the FX2 firmware seemed to 
support operation of another USB endpoint for additional data, like 
perhaps VBI outside of the mpeg2 stream.  The firmware in the new device 
seems to have removed the commands for operation of that endpoint :-(
