Using playvideo command multiple times produces corrupted/broken video output

[vrad-exe]

Describe the bug

When a video is played with the playvideo command, stopped, and then another video is played, the video output will become broken for the rest of the session. This usually manifests as nothing but the last frame of the first video being shown, but sometimes it will be discolored or mixed with the new video that's playing.

To Reproduce

1. Load a map (so vgui/panorama doesn't draw over the video)
2. Run playvideo sp_ending_callback
3. Run stopvideos
4. Run playvideo sp_ending_callback again
5. The video freezes or appears corrupted
