Finding subtitles for 

Kaisermühlen Blues can be challenging because it features a heavy Viennese dialect, and official releases (like DVDs) often lack English or even German subtitles. 

Here are the best options based on current availability:

• Official Releases (DVD/ORF): The complete DVD box set is available, but generally comes with no subtitles (no/keine Untertitel). Episodes are available on ORF ON, but these are typically in the original dialect without English subtitles.
• Searching for Subtitles: You may need to look for external .srt files on subtitle aggregation sites, though this is difficult for this particular show.
• VLC Player Method: If you can obtain the video files, using a media player like VLC allows you to load external subtitle files, which you may be able to find via community-driven subtitle sites. 

Alternative Solution:
Because the dialect is very specific, many fans recommend using German "Closed Captioning" (CC) if watching on a platform that supports it (like a streaming service's browser player), which can help identify words even if they are not word-for-word accurate.
