Hi, Arinkii. Good to see you too.
The only problem with it was that:
1. It doesn't save the configuration. That is, every time you turn on the camera, you have to dial in your settings.
2. Every time you turn video hack on, it will disable the canon audio automatically.
3. the flush rate is limited to 50, so you can't All-I at 60fps.
I never found the "locking the camera if it moves the flush rate/gop too fast" problem though. Caveat: You have to set the flush rate according to the framerate, or it WILL crash/lock up the camera. i.e. flush at 24 if you shoot 23.976
It used to be on TL up til about, what last month? And it worked well if you know what to dial in.
