To be able to record all channels that interest me at the same time, I have a DVB-T stick inserted. Two channels that are also on DVB-C are mapped solely to the DVB-T so I get no conflict between these ones and the other ones that I am interested in (which are all conveniently on the same transponder).

I only recently installed 1.1.0 SVNs as I did not want to mess up my almost perfect 1.0.2 setup, but a system crash forced my hand

Now, the symptomps... With all DVB-C channels, I can switch on TV, switch off TV, change channel etc...
With my DVB-T channels I can switch it on once. Changing channel does not work. Switching it off and back on does not work. Even starting Timeshifting from the TVserver Configuration fails. If I kill TVserver and then restart it, I get one more chance. Then I need to kill again etc...

Attached are my logs. I tried to do this with a "clean" system. Meaning: I disabled all plugins, I disabled 4_the_record (which I just started experimenting with) and I used Blue3-Wide. I am open for any testing that needs to be done.

Re: DVB-T cannot be tuned a second time

Yesterday I missed a recording because I tested this and then forgot to reset the TVserver.

So I started looking through my logs myself though I know nothing about the technical side of this

The big difference I see is this.

Succeeded tune

Now I wonder if this could be driver/hardware related, so over lunch I'll hop over to home and try the Pinnacle driver instead of the default Win 7 one. I might even take the stick with me to the office and run a test on my Vista laptop...

Stay tuned for more

Mental note: never trust M$ drivers !

Pinnacle driver solved the issue... If someone cares to edit the thread name or icon, feel free!

Re: DVB-T cannot be tuned a second time - driver issue

Well... I have to get back on this...

I still have an issue

It would seem that I can tune to ONE channel on EACH frequency. In my case, 8 channels on 2 different frequencies. When I thought it worked, I just happened to try a channel from the second frequency.

Now, I have no issue whatsoever with this on Vista 64-bit. But I confirm the issue on two different Win7 32-bit machines. I tried almost every possible combination of MP/driver/... I have the issue with MP 1.0.2, 1.1.0 vanilla beta and 1.1.0 last SVN.

I guess this is not really high-priority and probably not a common issue, otherwise it would have been reported. It's not a showstopper either, but if someone feels like taking this up, I'm around for testing.

I'm leaving on a prolonged NY-party-WE and I decided to do one last test. I changed the Preferred network provider to DVB-T ! This time it seems to just keep working.

Kudos to the developers for having given me the solution even before I knew there would be a problem !

Actually that was initially a patch from an active user So, the team wasn't doing any good in this case

Have you had troubles with usb tuner(mainly for that pinn... 72e), so that after restart it is sometimes redetected into tvserver and the old "instance" is marked as unknown.
If so, have you solved it some clean way ?

I patched tvserver a bit for usb tuner purposes, so that if tuner path has same device_id path is anly updated to current tuner instance. That way i don't have to rescan channells to possible usb instanses that tuner can appear.

But this is not a clean and good solution.

I think TvE3 should have some configurable option, or some other methology for dealing this situation.

Well, you deserve kudos anyway !


@te3hpurp: no, never had the problem you described. At least not yet. And I must say this DVB-T stick has worked wonderfully until I installed Windows 7. I'm leaving it running now for 4 days... we'll see !
