TV breaks when "No Signal Detected"

[qawaali]

Nielsen,

I don't think that will help you mate as I have the 150 not the 350. Have a search for 350 related problems and see what others are using.

With the 150 over time I have used the drivers that came with the card and whatever are the most recent on the Shspvr forum when I am having a play. They have all worked. This card has never given me any problems with the analgoue side of things in MP.

Sorry if that's not much help mate

Hi,

I have a clean build box with everything reinstalled. I have noticed that MP always says I have 0 signal but 75-100% quality. It autotunes fine. My humax box always reports vhigh signal and I plug this cable into the T200.

When changing channels - works fine then I get a channel that says "no signal" after which sometimes the system hangs - othertimes I can change channels - but even the channels that were working appear to stop and soon everything will hang with a big black screen.

I noticed in the log below the change from Sky travel to ITV3 was fine - yet the same key press to BBC4 seams to have created a different sequence .. after which the system had a black screen and failed to respond .. despite keystrokes happening in the logs and functions happening.. but the screen was blocked by the TV card hogging it un-terminated.

Hi folks,

I may be stating the obvious here, but are your power settings configured to power down the monitor/TV after 20 or 30 mins? I had the same problem and changing it to "Never" fixed the problem.

Synopsis:: No Signal Error Message

Hello,

I have suffered this problem since the 0.1.3 release. Mostly, I get the old
'No signal detected'/'dvbdemuxer: stopped receiving packets', at random times. The mediaportal.exe process refuses to die, and I can't get the tv-card to work again unless I reboot the machine. I got a decent DVB-T signal in my appartment, a few packets lost every now and then.

This seems suspiciously like a problem within Directshow's handling of live DVB streams, rather than just a bug in MP. Or a combination.

I have been having this problem too on 0.2 RC2 I have above 90% signal strength on all channels yet at various times the picture will go black & the "No signal detected" message will come up on the screen. This affects all channels on the DVB-T cards but also the composite input on the 150MCE & the only way to fix is to reboot the PC.

When I switch back to 0.1.3 all is fine.

I suspect this might be the same problem I have reported with recording in the thread http://forum.team-mediaportal.com/viewtopic.php?t=12950, because I had the recording problem last night but checked the status of mediaportal at the end of the recording, and the tv was displaying 'no signal detected'.

[FlipGer]

Hi,

I also have "No signal" from time to time while zapping around with both of my PVR cards (150 / 350). I have digged somewhat in the code, to get a clue what might going on.

There are two reasons for raising "No signal":
1) Lost of the tuner because of a bad signal
2) VMR9 renderer dropping down to 0 FPS

I always run into the second condition. Currently I do not have any clue, why this might happen. Any of the devs around there, with deep knowledge of the code?

Using latest CVS and timeshift off.

Flip.

[FlipGer]

Hi,

could you people please all test DScaler as renderer for audio and video?

As far as I could see, every body is using MPEG2Dec, InterVideo or NVidia. (including me using MPEG2Dec).

I did change the settings to DScaler and still got a "No signal", but i did need much more zappings to get it!

So please test and report, if it got better / unchanged / worse...

Flip.

[Paranoid Delusion]

Similar thing happening only on last 2 weeks cvs. also has affected lifeview software as will only pick up a few digital channels and crashes. if you uninstall MP lifeview works ok again. anyone with that happening to their own TV software, but if you leave lifeview software uninstalled and clean reinstall problem seems to be dramatically reduced, could this be because mine's a dual analog/digital card. PS do not use analog anyway

:cry:

[qawaali]

Flip,

I have tried it with the DScaler codec and I still had loss of signal. I have also tried with the DNTVLive codec same result.

For me and the DVBDemuxer stopped receiving packets error I believe it is a card / driver issue as I have been using a loan Compro DVB-T 300 for a week now and it works flawlessly.

In my case I would suggest / guess that the "no signal" code is indeed working as required I just need to find out why the connection between the DNTVLive card and MP breaks?

Having said all that I do occasionally get the No Signal error using my PVR150MCE via S-Video but taking into account your point about what causes the No Signal message to appear I believe that this only happens when MP runs a little sluggish (multiple consecutive channel change requests etc) which would suggest it is because of the VMR9 fps dropping rather than the actual signal being lost. The big difference is that the PVR150MCE will correct itself within a second or so whereas the DNTVLive requires me to restart the PC
