I'm using ProgDVB and updating as soon as a new release is available.
Updating from 7.31.2 to 7.31.3 made the program unusable for me.
The video is full of graphical artefact.
Here is a sample:

I can confirm the bug was introduced in 7.31.3 because I downgraded to 7.31.2 and the bug disappeared.
I'm using the 32 bits version and DVB over IP as a source.
Please help, just tell me if you need anything.
