Message: <blockquote data-quote="clarkebelt" data-source="post: 1091239" data-attributes="member: 148422">After changing all those frequencies to equivalent C-band frequencies, and making sure the band type is set to C-band (band="2" in the xml import file), they worked.  When the band type was set to Circular (band="1") and the originally scanned frequencies were used, they did not work.  This is only true with the TBS card, I did NOT have this problem with the Prof 7301.  So my guess now is that the patched drivers that allow the use of a DiSEqC switch somehow don't handle Ku correctly.Until this is fixed (hopefully that will happen at some point), for anyone else that might be having this issue, the way to convert a Ku-band frequency (from a standard Ku-band LNB, not a universal one) to the equivalent pseudo-C-band frequency is:Take the Ku-band frequency and subtract 10750  (10750 is the intermediate frequency of a standard Ku-band LNB)Take the result and subtract it from 5150 (so, 5150 - the result you obtained above)That result is your pseudo-C-band frequency.  But remember that for this to work the band type for the channel must be changed to C-band, and for some reason that is the one thing you can't change in the channel editor (I wish you could, or could at least see the current setting there, because it would have been helpful in figuring out what was going on earlier in this process).  What you can do, assuming you can understand the format of an XML file, is export all the channels to an XML file, then using a text editor remove all the channels that are not affected, change the band on those that are affected to band="2" (and change the frequencies to the equivalent C-band frequencies if you haven't done that already), and save the changes (preferably to a different filename so you have a backup of all your channels in case you have messed something up).  Then go back into TV Server and delete the original channels, and import the changes.  TV server will probably still complain that you have duplicate entries even after you have deleted the original channels, but there is nothing that can be done to make that warning go away as far as I can tell, so just import the changed channels.  Note that when you do this you may need to re-map any channel associations (such as for guide data).I would also guess that if you have never scanned a satellite and you want to scan a new one, and scanning it as Ku-band circular doesn't work (I would always try that first!), you can always try scanning it as C-band.  If that works it will scan in the pseudo-C-band frequencies right from the start.  This is certainly not an ideal method but if you are having this issue with a TBS card it may be your only workaround for now.</blockquote>
