As predicted earlier, German Company SPLENDID film has released DAS SCHWERT DES CID on DVD in 2.35:1 anamorphic widescreen.
Picture looks good:

Unfortunately, it is German Language only - the previous information that suggested it might have an English track, or even English subtitles, is quite wrong.
Guess who's looking for an English Language VHS in PAL.
Running time is quoted as 80 minutes, which would make it 83 minutes at the cinema. The imdb says it's 86, but who trusts them ?
It's directed by Miguel Iglesias (i.e Mike Church), but allegedly that's a temporary pseudonym for Ferdinando Baldi, adopted in order to get co-production cash from the Spanish government.
