Remove "0-original - H264 (undefined)" in download list

[acrawford73]

Describe the feature you'd like
When DO_NOT_TRANSCODE_VIDEO is True, there is a media download entry created called "0-original - H264 (undefined)".
This is confusing for end users who wish to download the content. For a better user experience, this should be removed, making it consistent with other video platforms. Only the "Original file (nMB)" should be shown, when DO_NOT_TRANSCODE_VIDEO is enabled.

Describe alternatives you've considered

Additional context
My use case is that all my uploaded videos are already transcoded with Handbrake to the desired format, compression, and file size for optimal storage. Therefore, I do not need further transcoding performed. In fact, MediaCMS 480p transcodes are larger in file size than my 720p file.

Thanks
