AC3 or DTS and subtitles question

[vegitossj5]

Does the remove HD audio option convert the audio stream into either a 5.1 ac3 or a 5.1 dts? My next question is if I pick the spanish subtitles in a main movie only option will I be able to turn them off and on during playback on my ps3? In other words they are not encoded on the video right? they are just like an option that can be turned on or off on the ps3. Someone please help

If the audio stream is AC3 true hd 5.1or DTS hd 5.1, the ouput file is AC3 5.1 or DTS 5.1.
For your second question, you can choose whether display the subtitle or not.
