I corrected the lnb.c files in both scan-s2 and szap-s2. I'm able to lock, and the scan has produced a channels.conf file. I will run more to see if results are consistent.

I've been running both szap-s2 and scan-s2 all evening, and I get variable results! Sometimes it will lock, sometimes not. Once I even got a scan with data in my channels.conf file. The next time it fails all scans! I'm not seeing any stability here. Something must be wrong - My experience...

Has anybody gotten scan-s2 to work successfully with the prof 7500? I need some comparison points here - maybe I expect results that can't happen? I need to build a channels.conf file for Mythtv. Thanks

Interesting... When running scan-s2 I have also run with the -5 option, which increases the time (Tho I'm not sure it increases the CORRECT time) per channel. At this point I'm just supplying one known working set of numbers and it still can't seem to return anything useful. See post #35 above...

OK, I got a fresh set of files from mercurial for scan-s2, fixed the API check (to 5.1) and it is installed. I still can't get good results, using the prof7500. Tune-s2 works great, get lock. What is up with scan-s2? Does this need to be modified to work with the prof? Here is what I get with...

I had a problem with scan-s2 from mercurial. I didn't look at the source, though. I got your demux program, but I haven't installed it yet. Can you think of any reason the assignments of the prof and the TBS card might change around after reboot? Or, is there a way to ensure persistence of...

Heh, the compiler barfed, complaining because the S2 API was not 5.0 (It is 5.1). So I didn't pursue that any farther. Maybe I pulled an old set of files?? I'm pretty sure I built both scan-s2 and szap-s2 from the TBS files. I can't get a sucessful scan, but I'm sure I'm doing something wrong...

Tune-s2 has been running almost 24 hours, the prof has lock and no problems. What app can I use to check the video?

updatelee, I just realized you were talking about scan-2, not the dvb-s2 files. I'm not sure where the scan-s2 came from, probably either the TBS or dvb-apps. I'll get scan-s2 from mercurial and try that.

That is correct. I'm going to just focus on the prof7500 because the devices change assignments every time I reboot or make any changes. I wanted more than one tuner to handle both sat and local OTA HD TV antenna stuff. I didn't know if there were any other files needed for the prof. Thanks...

updatelee, can you tell me which files are needed for the prof7500? I just killed it by rebuilding the modules. ARRGH!

It sure does! tune-s2 12060 H 26700 -adapter 2 -lnb STANDARD LNB: low: 10750 high: 0 switch: 0 opening: /dev/dvb/adapter2/frontend0 LOW band Tuneing specs: System: DVB-S Frequency: 12060 H 26700 22khz: OFF Modulation: QPSK FEC: AUTO Inversion: AUTO Rolloff: AUTO...

Eh, ya caught me! I've gotten confused more than once... The TBS card is dual, it maps to Adapter0 Adapter2 The Prof shows up at Adapter1 Yet Mythbackend identifies them differently, in different order. Doesn't matter as all scans fail with myth anyway. Clear as mud?:D

updatelee, I ran tune-s2, and the TBS card appears to tune just fine: tune-s2 12060 H 26700 -adapter 2 -lnb STANDARD LNB: low: 10750 high: 0 switch: 0 opening: /dev/dvb/adapter2/frontend0 LOW band Tuneing specs: System: DVB-S Frequency: 12060 H 26700 22khz: OFF Modulation: QPSK...
