T3i Dual ISO raw video aliasing

[tbreade]

Hi everyone.

I was testing Dual ISO feature in raw video mode and got some issues.
There is aliasing in highighs and tiny blinking spots.





Here is what it looks like in motion:

Used october 05 nightly build, shot in 50p mode with fps override to 24 fps, resolution is 1344x320.
I searched the forum and couldn't find any similar reports. Am i doing something wrong?
There is no such spots in regular raw video or dual ISO photo modes, only when combined, if that helps.
Original DNGs: before cr2hdr http://www.sendspace.com/file/jicb6w and after http://www.sendspace.com/file/wwdfye

p.s. I also get broken magenta frames every now and then.
p.p.s. Sorry for bad english.

Try using ISO 100/400 or 100/800.
