I have seen a few post about TVService being lost, but they are from older MP versions, or they occur while using MP.
My error only happens after wake up from suspend, so I decided to open a new thread. I will try to explain it better:

During normal use, MP works fine and never losts TVService. But quite often (not always), when MP wake up from suspend to EPG grabbing or to record an scheduled TV program or because I manually switch the PC on, a message box appears: "TVService have been lost" (in Spanish).

The effect is that this message keeps on screen, and what happens then vary:

1. Sometimes, I hit the ok button and then I can use MP normally.
2. But sometimes, MP hangs and then I have to press Alt+F4 to exit MP and run it again (without restarting the PC).
3. And very few times, I have to reboot computer.

And of course, if a recording is scheduled it is not recorded properly.

So it seems that the TVService is still running properly (cases 1 & 2), but MP is not able to reconnect to it. If this is the case, would it be possible to make that MPs keep trying to reconnect to TVService several times and if successful, just close that message box? If no, it could restart the PC...

I have the TVService configured at Windows to restart if it is stopped.

This afternoon I was trying to reproduce another bug, and this happened again when I manually wake up the PC, so I have "fresh" logs. If you look at logs, it happened at around 20:34.

I also have found that there is an event error in Windows at that time (sorry, but it is in Spanish):

If any developer could have a look to my logs to try to find something, I will be very gratefull. And if you need any further information, please do not hesitate in asking me.

Thank you for all .

Do you have a static or a dynamic IP-address on your system? I had some major problems when my single-seat-system returned from suspend when having DHCP IP-address. The lease on my DHCP-server was 1h and when MP was asleep for more than 1h it got a new IP-address, then MySQL or TVServer lost connection and got rather strange errors.

Looking at the errors it looks like it failed

which would tie in with this crash

<Data>Sky2PCAVSrc.ax</Data>

This would appear to suggest it is actually the skystar2 filter which has crashed

Are you using the latest drivers?

This ties in with some errors in TV service which restarts just after this

2010-10-16 20:35:37.842773 [(5)]: TV service: Starting

but it looks like this happend after your machine went into standby for about two minutes? Have you set the restart TVservice on resume option?

Also are you using any firewall which might be blocking connections?

Finally I noticed an issue about not being able to connect to database, could you just check your database
Open up a command prompt (as admin if Vista / Win7)
navigate to MySQL Bin folder (is C:\\Program Files\\MySQL\\MySQL Server 5.1\\bin for me) and enter

mysqlcheck --user=root --pass=MediaPortal --auto-repair MPTVDB

Lots of thanks for your kind help.

melstig: I have a DHCP address. I will try a static one...

jameson_uk: I completely restart my system on September (previous HD died), and I downloaded latest drivers for everything. The skystar2 driver is 4.6.0, from 17-05-2010. I have just checked the TechniSat website and this is still the last driver.
Next time I get the error, I will try to watch one of the sat channels to see if it is alive...
In my test, I wait a couple of minutes to wake up the system, but other times it was sleeping hours.
I don't have set the restart TVService on resume. I will try it...
I don't have any firewall, except the Windows 7 firewall. My antivirus system is Microsoft Security Essentials, and I don't think it blocks connections.
I run the SQL command and it reported everything OK.

So I will try in turn the two things you have suggested (static IP, restarting TVService), and I will report here my results. It may take a while as it is a random error not happening every day.

Thanks again for reading all my long logs

Just a quick answer to tell anybody interested what it is happening:
Before trying these things, I disabled the EPG grabbing from sat channels. And the error never happenned again.
So I think that it is clear that there is some problem between the skystar2 filter and TVService. When the skystar2 filter crashes, it provoques TVService crash.
So I think that there is also a TVService robustness issue.
I cannot keep testing it because other issues arrived (https://forum.team-mediaportal.com/...scheduled-recordings-other-rare-issues-90034/). As soon as these new issues are solved, I will be back to this one.

Hmm...
I also had lots of "TVServer is lost" problems on resuming with all 1.1.* versions.
To be frank, TVServer never worked correctly.
Moving to MediaPortal 1.2.0 ALPHA solved my problems.
I also have SS2, dynamic IP and DVB EPG turned on, except for "when idle".
Unfortunately, now I can't listen to music

 

[mrspock]

bounguine: Could you tell us what version of SS2 drivers do you have in your system?

 

[bounguine]

1753 wdm

 

[mrspock]

1753 wdm

Thanks, but... my WDM driver from Technisat is 4.6.0.9999 dated 28/April/2010 (obtained from Device Manager). I don't understand why numbers are completely different.

 

[bounguine]

I gave you the number of the dustributive from their site.
What you posted is a driver version (mine is 4.5.0).
Anyway, I don't think that is a driver issue.
TVServer stoppped working when I upgraded from 1.0.2 to 1.1.*
And then started working in 1.2.*
But I didn't change SS2 driver.
Moreover when downgrading from 1.1.* to 1.0.2 also solved the problem
