Quick tutorial to turn a downloaded (or ripped) MKV into a DVD (but in HD) playable by the Playstation 3 or most newer Blu Ray players. The benefit to this over streaming is that the downloaded (or ripped) file is often of a higher quality when played directly on the PS3. Streamed video is usually degraded in terms of bit rate often noticeable on action scenes.

Step 1:
Download tsmuxer
http://www.smlabs.net/tsmuxer_en.html
Download ImgBurn
http://www.imgburn.com

Step 2:
In tsmuxer on input tab click add, browse to the file.
Under tracks click on the first file and change the level to 4.1 or below.
Under output click Blu Ray disk
Click start muxing (should take 2 min)
Two folders are created (BDMV and Certificate)

Step 3:
Open Imgburn
Click Write files/folders to Disk button
Click add folder button (yellow folder)
Add both folders created by tsmuxer
Under options tab change File System to UDF
Only have "Recurse Subdirectories" checked.
Click the burn button at the bottom.
