[linux-dvb] bug in szap-utility

Hi folks,
as part of the Debain package dvb-utils 1.1.1-2 the szap utility has the following bug:

1. The start transponder file of Eutelsat Hotbird13.0E contains a "H" as description of the polarization.

2. Unfortunately this "H" is being interpreted as "V".

3. So if you try to produce a transponder list with the start transponder you are trapped as nothing works!

To see the error yourself, try the following example in the console:
szap -r -a0 -c trapz.txt -n1

where trapz.txt looks like this:
Hotbird-13.0E:12539:H:1:27500::::

In the console you will see the right frequency and the right symbol rate.
But the polarization will be printed out as "V" (vertical) instead of "H" (horizontal).

In other words: The bug is: szap cannot set equal the letter "h" with the letter "H"

Regards

Uwe

P. S.: I solved the problem by a TCL-TK workaround, but it rather should be solved in the sourcecode,
shouldn't it? So can someone reading this please fix that bug in the source code?
