Wow! It really works. Thanks alot!

My test results:
I'm using 4GB SDHC card, class 6.
In the bitrate setting, i'm able to get to 3x with no problem with about 5500KB/sec.
In the quality setting, 99% seems too much for the camera and it fails to operate like said before.
The maximum possible quality is 96%.
97% starts to build up the buffer on the screen until it becomes red and stops the recording.
I have some questions:
1. The squares on the right building up until becoming red is the warning buffer right?
2. What's the fast video control setting ?
3. In the ZIP package there is a PS.FI2. Does it mean i can run CHDK on my 16GB card using "firm update" mode? (and not by bootable card)
