Raydel,
Apart from the frequency and signal level differences, DVB-T is a 6-8MHz wide signal with COFDM modulation, using 2k to 8k subcarriers, while DVB-S is a single carrier, 6..36MHz wide signal, usually QPSK or 8PSK. You cannot use a downconverter and a DVB-T receiver to tune into a DVB-S channel.
However, the digital bitstream carried by both is the same - so if you have software analyzers and audio/video players for DVB-T they will work for DVB-S too.

Hello,
About the future HamTV experiment, is it possible to use a cheap RTL DVB-T dongles used or RTLSDR to receive such signals with proper LNA and downconverter. If the downconversion fits the signal on a proper channel does it device is capable of decode the transmitted format???
Thanks,
Raydel
