Hi Steve.

I have more news to report.

I have hacked some extra args to the kromtek multiproto szap and am able
to tune to a DVB-S2 channel.

However, I can't actually tune to a channel I am able to view, just
get a lock on, so someone else must confirm that it actually streams
correctly.

An updated szap is here:

http://dev.kewl.org/tmp/hvr4000/szap2.tgz

An example use:

# szap2 -x -a 0 -r -c ./Astra-28.2E.conf -t 2 -e 3 -m q "Sky HD Promo"
reading channels from file './Astra-28.2E.conf'
zapping to 1 'Sky HD Promo':
sat 0, frequency = 12324 MHz V, symbolrate 28250000, vpid = 0x0200, apid = 0x0280 sid = 0x0ed9 (fec = 64, mod = 2)
Querying info .. Delivery system=DVB-S2
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
FE_DISEQC_SEND_MASTER_CMD failed: Operation not supported
FE_DISEQC_SEND_BURST failed: Operation not supported
----------------------------------> Using 'Conexant CX24116 DVB-S2' DVB-S2
do_tune: API version=2, delivery system = 2
do_tune: Frequency = 1724000, Srate = 28250000 (DVB-S2)
do_tune: Frequency = 1724000, Srate = 28250000 (SET_PARAMS)


status 1f | signal 008c | snr 0000 | ber 00000000 | unc 00000000 | FE_HAS_LOCK

The args to make the hvr4000 work are:

    -f        : fec (1=1/2, 2=2/3, 3=3/4, 4=4/5, 5=5/6, 6=6/7, 8=8/9, 0=AUTO)
    -m        : mod (q=QPSK, 8=8PSK)

If anyone can confirm that it works on FTA DVB-S2 that would be useful.

cya
