No.

When the stream starts, for the first second or so the demod delivers 
junk, this is normal across many different 1409 based designs. After 
that dvbtraffic is reporting consistent bitrates and pids on the machine 
I'm testing on.

It's looking good for me, 38Mbps spread correctly over 3 video pids, 
padding on 1fff and low volume PSIP information on 0, 1 as well as 
200kbps audio channels.

Channels are encrypted, but the rates look perfect.

Hmm. No, I have pushed those up. Sorry, my mistake.

I'm expecting another user to test later today and report back.

(from memory the patch really just adds the 800i define to operate the 
same as as the HAUPPAUGE HVR3000 in cx88-input), mainly because the 
silicon is the same - it should just work.
