[linux-dvb] max. symbol rate

[dynamite <dynamite@efr-net.de>]

Hi everyone!

Today I turned around my dish some degrees to try Hotbird.
I used dtv_scan to create a channels.conf for VDR. So far everything looked
fine, but then I noticed that some transponders were missing. I checked out
www.lyngsat.com and found out, that these transponders (e.g. TP 110) are
using some 'exotic' symbol rates like 29000.
I wanted to create a channel from this transponder via the VDR osd, and
that's what this is all about: the maximum I was able to enter was 27500.
This is a very minor bug, but if someone cares about it, or just wants to be
sure, that you could tune such channels, though you really have no idea why
to watch EWTN or something :) here's a patch:

      Add(new cMenuEditIntItem( tr("Apid1"),        &data.apid1, 0,
0xFFFE));


The reason why dtv_scan couldn't find channels on these transponders is due
to the transponders.dcl where these transponders are listed with a symbol
rate of 27500. I changed that for TP 110 to the right value and everything
worked as expected.

Enough for now, I'll keep looking for treasure on Hotbird :)
