[linux-dvb] Nova-T PCI rev 1.2, CVS DVB driver, Alpha and PowerPC

[Paavo Hartikainen <pahartik@sci.fi>]

My experiment with Hauppauge Nova-T (model 909, card revision 1.2) has
not been completely successful.  I have managed to "scan" local
multiplex A, to create channels.list, but it still gives me no
sensible video or audio data within MPEG-2 TS.  MPlayer says "MPEG:
FATAL: EOF while searching for sequence header.", but it sees PIDs
("VIDEO MPEG2(pid=512)...AUDIO MP2(pid=650) NO SUBS (yet)! PROGRAM
N. 0") that got saved along broadcast data.  MPEG-2 TS (~60 seconds,
~20 MB) was captured on PowerPC by "cat /dev/dvb/adapter0/dvr0 >
~/ts.data" while "tzap" was tuned to
"[0011]:578000000:INVERSION_OFF:BANDWIDTH_8_MHZ:FEC_2_3:FEC_NONE:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_8:HIERARCHY_NONE:512:650:17".
Nothing got captured when I tried same thing on Alpha.

Usual "tzap" output, no difference between Alpha and PowerPC:

That "ber" value looks strange, it is always "0000ffff", even if I
run "tzap" with antenna unplugged:

Only multiplex A seems to be available, others I have not been able to
"scan" or "tzap" to.

Kernel is Linux 2.4.23 on both workstations.

Any suggestions?  I will take this DVB-T tuner back to the store and
look for another revision or model if I cannot get it to work within
few days.
