The Bonzai DVD, from what I can tell, seems to be taken from the US Xenon video release... which in turn, was a hybrid. Let me explain:
The Xenon video release uses the German VHS print titled "Bruce Li - Die Killerkralle", which had a 2.20 widescreen print... but was censored. Using this German print is the reason why Xenon freeze framed the opening with their own "SOUL BROTHERS OF KUNG FU" logo. But, the English dub is most likely taken from the 80s US Prism video release titled "Kung Fu Avengers". You can hear jumps in the audio quality in some scenes. Hell, when Bruce Li's character says "To get revenge!" to Ku Feng's character before their final fight, you can tell it was ripped from the scene where Li was training... you can hear the weight plates clanging! Meanwhile, there's a video on YouTube that mixed the widescreen footage, the uncut ending... and The Crystal Method
