When I start my HTPC, and then MP (no matter if it starts automatically or by hand), and go to My TV, i get no picture, even though TV is enabled. I have to disable TV, and enable it again. after that i get a perfect picture, and everything works as expected. i can even close MP, and start it again - everything is fine. until the next restart, after which the first activation of My TV fails again.
This makes it impossible to do any automatic recordings with pvr-scheduler, because it does not receive a correct video-stream after startup.

what i get in the logs is a _very_ long list of "wait for pmt: -1". i checked the pmt-ids in my channel configuration, and they are all filled out, and look correctly.

i already tried the option in power-scheduler to restart the tv-engine on resume, but it does not seem to do anything on a plain boot from soft-off.

when i start Terratec Homecinema instead, i get a picture at the first try.

any ideas how to fix/workaround this?

We need the logs.....

 

[Eabin]

of course!
what i did for this log was
*) turn on pc
*) start mediaportal svn
*) go to my TV
*) wait a few seconds (10 or so)
*) don't see a picture, and no sound
*) turn off tv
*) turn on tv
*) voila, picture and sound
*) close MP

what's weird is that you get a very poor signal quality , the first time you are entering mytv :
18.09.2006 17:07:14 968 [Info.] DVBGraphBDA: signal strength:100 signal quality:8 signal present:True locked:True

... and don't get the pmt...


Did you try disabling 'Hardware PID filtering' in the card options config?

use MPV and MPA as Video/Audio codecs
thats exactly the behaviour i get with Intervideo (Windvd7) codecs.

thanks for the suggestions.

changing audio/video codecs didn't help unfortunately, and i couldn't find the option to turn off hw PID filtering. is it supposed to be in MP-Setup, under TV->Cards->Edit?

other than that i had some success when I manually disabled TV and closed MP before shutdown, but that didn't seem to work reliably either.

is the card not correctly initialized, or is there anything in particular that "pmt: -1" indicates, which i could try to change in the source (maybe put some explicit re-initialize cards code somewhere after startup?)

this option is only shown if your card supports it. and your card doesnt

When have this issues started? Do you have the same problems with plain 0.2.0.0 final too?

 

[Eabin]

just did a clean uninstall / install of MP 0.2.0.0, and the issues remain the same

could this be related to a too high signal level? i have read this in other threads, but before going out and buying a damper, can anybody tell me if this could be a possible cause for my problem, and if so, is there a utility to test the signal level?
