Problems with subtitles on Windows 7

Hi there!

I recently performed a clean install of Windows 7 on my machine, and proceeded to download and install the latest K-Lite Codec Pack Mega. But now I have two problems regarding subtitles.

The first one is when I play a video in fullscreen, the subtitles get really blurry. It's like the subtitles get stretched with the movie. Here's what I mean: https://i.imgur.com/dV8d3Kp.png If the movie has really high quality this is not noticeable.

The second problem is that I can't download subtitles pressing 'D'. That option is "greyed out", like it's disabled.

Thanks in advance!!

Both problems are because the internal subtitle renderer is not being used.
Options > Playback > Output > select "Advanced Video Renderer (custom presenter)

Did you get a warning message during installation about your graphics driver?

Thanks! Problem solved (Just a small correction, the option was Enhanced not Advanced)

My laptop has an integrated (intel) and a dedicated (ati) graphics cards, I haven't installed the dedicated drivers yet..

Was the correct Intel driver already installed prior to the codec pack?

I installed it through Windows Update. I'm not sure.
