Nothing but boxes

I leave all the videos that MCEBuddy processes alone unless they are MKV. So I have a show that was 2 hours long, 720p, and 2.3GB in size that I was converting to WMV. When it was done converting, the whole video was watchable, but the whole screen was like a grid of boxes. Came back as 3,470kb/s, 1280x720 so not low quality outbut but the result looks low quality none the less Thoughts? I’d attach the conversion logs but don’t see an attachment option.

Thanks.
