What is the real difference between these two barcodes? I don't get it.

1) ISBN bar codes have the book's ISBN, starting with "978," underneath/above the bar code
2) UPC bar codes have groupings of five numbers under the lines of the bar code, instead of groupings of six numbers like on the ISBN bar codes
3) CueCat's "gibberish" output includes "cGf2" in the middle if the bar code is an ISBN bar code
Now, if I'm correct about that, it makes it very confusing to try to wrap my head around this problem: I've tried scanning three books, of which 2 are paperbacks and one is a hardcover. All three books have a number beginning with "978" under the bar code on the back cover; all three have groupings of six numbers (not five) under the bar code, and all three put out similar strings of "gibberish:"
.C3nZC3nZC3n2CND0DxP1DxnY.cGf2.ENr7C3bWC3D0Dhz6E3PZCNnZ. (Paperback 1)
.C3nZC3nZC3n2CND0DxP1DxnY.cGf2.ENr7CNT7DNn0CNvXC3zYCxP2. (Paperback 2)
Only the hardcover comes up with any result at all. For the other two, the CueCat seems to take away the 978 and other numbers on its own, leaving me with a number that doesn't work with LT. For example, when I scan Paperback 1 into the "Add Books" box, I get "CueCat entry: 0330477595." Paperback 2 results in "CueCat entry: 1885071620." These are basically the ISBNs with the 978 removed. The bar codes look exactly the same, and there is no "ISBN bar code" on the inside cover of either of the paperbacks.
I have scanned other paperbacks with similar bar codes and they are O.K. (thank heaven; I was getting really upset, as the vast majority of my books are mass market paperbacks, and if the CueCat was going to reject all of them, I was in trouble). I don't understand what, if anything, makes CueCat misread these two bar codes. Has anyone else had problems with nearly identical bar codes just refusing to give the right result?
For Paperback 2, the scan resolves to 9781885071620 or 1885071620 (in this case, the check digits happen to match). That should be Pocket Ref.
When you say the number "doesn't work" with LT, where is it failing? Are you attempting to add books through a source like Amazon or Overcat, or a smaller library?
Actually, if you're getting books from the library, add your library to your sources. It's probably available, and will give you pretty close to 100% results.
