I have never done this before, but I am writing a review specifically to tell you not to try to watch "La Vendetta di Ursus" (or "Vengeance of Ursus") from a particular DVD producer. That's because I found the DVD to be completely unwatchable and of such unacceptable quality I just gave up trying to see it.
Not surprisingly, the film I tried to see was from Alpha Video. Alpha is known for producing films that are in the public domain. And, since they are such a cut-rate producer, they do absolutely nothing to clean up the prints, nor do they provide any DVD extras or captioning. The only way I'd ever recommend them is if no other company has released the film--and unfortunately, this is often the case. The films they do bring us are wonderful to lovers of B-movies and silents...provided the prints are watchable.
The film was scratchy, completely bleached (you could barely tell it had even once been a color film it was so bad) and the film repeatedly jumped--with missing bits and pieces throughout the film. While I can ignore the scratchiness and washed out print, because often portions of sentences were omitted and the scenes jumped about due to missing frames, I just gave up and recommend you find another version if possible or just skip it entirely. After all, there must have been 29123491324 different Italian muscle-dramas from the era starring the likes of Hercules, Maciste, Ursus or Samson.
