Wilson Leung Posted March 15, 2021 Share Posted March 15, 2021 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? Quote Link to comment
Griga Posted March 15, 2021 Share Posted March 15, 2021 Please reproduce the problem in DVBViewer debug mode, then attach a support.zip here. Quote Link to comment
Webturtle Posted March 15, 2021 Share Posted March 15, 2021 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 Webturtle Quote Link to comment
Wilson Leung Posted March 15, 2021 Author Share Posted March 15, 2021 Unfortunately it is PCIE TV card. I guess I will do the driver reinstall first. Quote Link to comment

Griga Posted March 15, 2021 Share Posted March 15, 2021 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? Quote Link to comment

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. Quote Link to comment

Thank you for the help. Quote Link to comment
