[TV] SD and HD channels are tuned only after 2nd attempt if transponder is changed (1 Viewer)

[cybernn]

Today returned on 1.0.2 and a switching error disappeared.

 

[cfforce]

Yes, same here, got 1 system with 2 boot drives.. one with the latest SVN on it; and one with 1.0.2. the 1.0.2 gives no problems at all with switching TV channels, both same windows version; (made a clean version with all updates installed and MySQL; and copied over to the 2nd drive.; then installed different versions of MP)

When switching channels on same transponder / freq. there is no problem; when you want to change to another transponder / freq. then errors in log:

2009-10-25 17:07:01.475838 [4]: dvb: LockedInOnSignal waiting 20ms
2009-10-25 17:07:01.507038 [4]: dvb: LockedInOnSignal waiting 20ms

2009-10-25 17:07:03.535038 [4]: dvb: LockedInOnSignal could not lock onto channel - no signal or bad signal

Only way to switch channel is to stop live tv first and then zap to another freq..

Got 2 tuners (firedtvs2) so there is no problem, only looong zapping time, cause it first can't tune in @ 1st tuner, then he goes to 2nd tuner..
But @ 1.0.2 it's going good.. it stays at tuner #1.

It's not a codec thingy; cause when u try it @ TV-Service the same happens. (manual > start timeshift)

The other card i've got here; a SkyStar2 seems to have not that problem.! (???? maybe only HD tuners are affected ?????)

It would be useful to get two logfiles showing the same steps:

tune SD -> tune HD

one log from current (non working?) and one from 1.0.2 version (working).

 

[cfforce]

I'm gonna make tommorow the 2 logs; but it's not only SD >> HD its from freq. >> another freq.. doesn't matter if its SD or HD. Also @ scanning for channels u can notice it. 1st freq. is scanned and 2nd not etc. (also confirmed by several users.); and it's not that there's not a channel on the 2nd freq. because @ skystar2 it works.

 

[morpheus_xx]

I think I have a clearer idea now:

        //put the Tuner request parameters to the driver
        ch = SubmitTuneRequest(subChannelId, channel, _tuneRequest,true);
        //set the DisEqC parameters[B] (Note: moved, some drivers require this to be set AFTER the put TunerRequest[/B]
        if (_conditionalAccess != null)
        {
          _conditionalAccess.SendDiseqcCommand(_parameters, dvbsChannel);
        }

--> diseqc is sent after tune

moving it back should fix this for you, but we have to check why it was moved thereafter....

 

[cfforce]

Mmmm.. this sounds good morpheus! it's seem logical to first diseq and then tune.... Im not a programmer; and i don't know how i can check this if this is solved in that way. (only relying on Svn's builds), if u can make a changed file of this; im happy to test it!.

I can confirm that 1.0.2 worked fine for me. I also went back to it temporarily and it worked OK. Version 1.1 has always produced this error which I have learned to live with in the meantime (waiting for a fix!).

On a related note, I think the single most important development MP could make is to improve the switching time between channels. This is the only 'feature' which makes me question using MP compared to a standard set-top box. If I've missed something and there is a way of tweaking the TV config to speed up the switching speed, I'm all ears.

 

[morpheus_xx]

please try the attached tvlibrary with the current svn build.

post back your tvcard model and if it is working for you!

 

[cfforce]

OMG! Morpheus! it works! And fast zapping!

Thank you very much.. i think you made quite some people happy!.. I hope that other cards also keeps working....

edit:
also modded my friend's system; and also no problems there after this fix.

This is awesome. I cant wait to get home and try this. Now you guys just need to nail the live555 issue and go RC1

Thanks
