Hi,
I'm not sure this is the right place but there are no user mailing lists
anymore for V4L?
I have a Gigabyte GT-PTV-TAF-RH rev d0 card that others report as
working since long time.
01:07.0 Multimedia controller: Philips Semiconductors
SAA7131/SAA7133/SAA7135 Video Broadcast Decoder (rev d0)
I loaded this card using the wrong card identifier, I used 78:
card=78 -> ASUSTeK P7131 Dual 1043:4862
and DVB-T worked for a while.
Within a day DVB-T stopped working:
$ dvbv5-scan nl-Free
Cannot calc frequency shift. Either bandwidth/symbol-rate is unavailable
(yet).
Scanning frequency #1 618000000
Lock (0x1f) Signal= 0,00% C/N= 77,65% UCB= 50886 postBER= 131070
ERROR dvb_read_sections: no data read on section filter
ERROR error while waiting for PAT table
VLC output:
[00007fa784005eb8] ts demux error: libdvbpsi error (PSI decoder): TS

CRC_32 table 0xb7 !!!
[00007fa784005eb8] ts demux error: libdvbpsi error (PSI decoder): PSI
section too long
To get output using card=78, I had to connect the cable to the FM
connector; it has an "FM" and "TV" connector and I had to use the "FM"
one to get DVB-T signal I could lock on to and successfully scan and
view in VLC.
With card=81, this is now the "TV" connector, as it should be of course,
but I did not know that in advance.
However after about 6 hours of usage the functioning ceased and I got
the above output on the FM input (that was working before), and now with
card=81, I get the same output on the TV connector. Consequently, I
tried using this card in Windows XP SP3 32-bit, for which there are
drivers, and no functioning; I did not test prior to this failing in
Linux.
Did I wreck my card by using the wrong card= selector?
Would there by any way to reset this card to its default state in that
case?
