Video distorted

[Wilson Leung]

I recently bought and installed DVBViewer.  It works great but I am seeing increasing distorted video like this.  Anyone has any idea how I can fix it?

Please reproduce the problem in DVBViewer debug mode, then attach a support.zip here.

Hello,

 

this could be a problem with the receiver or the driver. If it is possible a new start of the device could solve the problem. In the best case of an USB-device you could unplug an replug it. Sometimes my DVB-T2 HD Sticks are hanging and produce souch nonsense.

 

 

Many greetings

Unfortunately it is PCIE TV card.  I guess I will do the driver reinstall first.

How do I enter debug mode?

Never mind.  Reading instructions ?

Repro the issue in debug mode and Support.zip file attached.

You are using the Microsoft Video Decorder. Go to Options -> Playback Components -> Video -> Video A -> H.264 Video Decoder, select the LAV Video Decoder, click Apply. Does it work better?

 

If not, have a look at the DVBViewer Filter property page. Does it report a continuously increasing number of discontinuities?

Changed to LAV Decoder, same issue.  Yes discontinuities keep increasing.

DVBViewer gets a corrupted stream, either because reception is bad (check your antenna cable and antenna) or because the driver of your DMB-TH Tuner is losing data. Possible reasons are

• other drivers that are taking too much time while Windows is processing the chain of interrupt requests (try to temporarily deactivate devices that are not mandatory for your PC in the device manager, particularly network adapters).
• by a high CPU load (check it in the task manager)
•  by a low CPU load and energy settings (also in the BIOS), that let the CPU temporarily change to deeper sleep states, so the timing requirements for real time processing can't be fulfilled anymore (the broadcasters don't wait...). In this case increasing the CPU load somehow would fix it.

Interesting, I have a TV signal booster, it was turned off, once I turned it on, the issue is gone.  Seems caused by bad signal.  Thank you for the help.
