As the thread title explains, when I watch TV for a while, then switch to the guide to see what else is on, the TV video and audio begin to studder in the small video window. Not sure if this scenario would create entries in the logs, but have attached one if it is of any help. Please ask for what ever else logs you require to aid in addressing this bug. Thank you.

    Got that problem too. Happens if I scroll down really fast.

    A performance issue - not likely going to be fixed in MP1. In short - fetching the EPG data is most likely blocking the rendering thread.

    I have a real nice sawtooth graph tooo, whenever I watch TV on a screen with the little preview-window. In fullscreen it is pretty much flat with no dropped frames. And it's not just in the EPG screen, also in recorded tv, music etc. Running 1.2.0 Alpha.

    This is ONLY on my HTPC with integrated Radeon 3200. On my laptop the graph is smooth in both fullscreen and preview.

    valtam: Run MediaPortal in windowed mode and make some screenschots with Shift + 1 running to show the graph. Post here :)

    First, thanks for your quick reply.

    What do you mean by "fetching EPG data"?
    Getting it out of the database or from DVB?

    Im using the clickfinder program and disabled EPG over DVB function in the card config.

    EDIT: Has it got something to do with this?: https://forum.team-mediaportal.com/.../gpu-accelerated-loading-fanart-images-88588/

    Was happy to test the Alpha, but I've gone back to 1.1.1 as this was starting to get pretty annoying. Still looking forward to 1.2 :)
