This is what I've found:
I have the Ultra connected to C/Ku combination LNB.
Tuned to G11 at 91W. Am sitting on C band channel Horizontal polarity channel, watching WB on the tv hooked to the Ultra.
Legend receiver is "stuck" on Ku band, because the front buttons wont let me move off of Ku. OK fine. There are 2 sats programmed in Ku on this thing GE K1 and GE K2 (whatever that means).
Went to Radio Shack and bought a DC block, and installed it on back of Ultra's IF loop output port. RG-6 cable goes to Legend reciever's Ku input port.
I am on the K2 selection. I can cycle thru 32 channels. I get to channel 32, and get a torn up signal. Looks like the old days cable scrambled picture where they take out the horizontal hold... I can adjust the Mhz up and down on the analog receiver, and go up to +6mhz and thats the best I can get. No picture lock, but I can adjust the sound and can hear that it's the NBC nightly news. That has now ended, and currently it's a bit after 7pm, and I hear a tone off and on... probably a slate showing the transponder etc.
Now, if I go back to the ultra, and move off of "H" polarity, I lose the signal. If I move from Universal 1 to Standard, or even C band LNB freq, nothing changes on the analog box. How strange is that???
I would have expected the Ultra box to adjust the LNB freq, but all I can really seem to change to have an effect is the H or V - no matter what band C or Ku, or transponder freq I pick - the result is the same.

I may be remembering this wrong, and confusing it with VCII video, since it's been many years since I fooled around with this, but your description of the video sounds somewhat like what I remember seeing if you were watching Ku on the C-band input or visa-versa. I forget the details, but I think it is because one of the two has reversed video, and since the pulses that the receiver looks for to sync are going the wrong way, you get a rolling or angled image. I know that you plugged into the Ku input, however in that receiver it's possible to set the KU input up as a C-band input, which might be the case. You might try tuning your DVB receiver to a C-band satellite, and see what you get, as it may actually be doing C-band through the Ku port. There is a lot more analog on C-band anyway.
Relative to your expecting the DVB box to change the lnb freq, etc, that's just not the way it works. The Ultra just passes through the whole band and doesn't change it at all. THe only thing it can do is tell the LNBF to switch polarity or change bands. It can't change the freqs, except by switching between local oscillators.
Anyway, finding analog on Ku isn't easy. If I notice any analog, I'll post. Your best chance is during these preseason NFL games. SBS6 is a good place to look, and all the sats between IA6 and SBS6 are possibilities. Not sure if there are any NFL games today or not.
EDIT: Oh yeah, the K1, K2 thing.. I think they are pretty much the same format, as there used to be a Satcom-K1 and Satcom-K2 sat (precursors to the GE 1,2,3 sats, which became AMC), and I think both had pretty much the same format. The weird thing on MY Echo/Houston Tracker receivers was that the receiver format had 32 channels, but it repeated. Ie I'd get the same thing on channel 16 that I got on 32. There was also an Anik format that had one polarity on 1-16 and the other polarity on 17-32, which was strange too. Then I think the SBS format, I think only had 20 channels. I think there was also a spacenet format too, there were about 5 different formats. Actually, I could set up a satellite to use C-band spacing with the Ku input too (this is different from the port being defined as C or Ku).
