Bug: Batch Subtitles Checkbox Enable/Disable Issue

[GiBiT]

Repeatable Steps:

1. Click Batch Subtitles Tab
2. Highlight a File in the List
3. Click "Use input file subtitle stream" to turn on the checkbox
4. While that's checked "on" Click on "Burn Subtitles" and now both are active
5. Now Uncheck "Burn Subtitles" -- Now notice that "Use input file subtitle stream" is disabled.

You can no longer replicate the initial functionality where both checkboxes are not checked and both are not disabled. "Burn subtitles" MUST be checked to disable "Use input file subtitle stream"

So either the issue is initially "Use input subtitle stream" should be disabled so that "Burn subtitles" must be clicked, or there is a minor bug with the interactions between the checkboxes and how they're disabling each other.
