1 & 2 / First of all, I have to reccomend you to use the latest nightlies. I had more stable recordings by sticking to the latest nightlies.
Thanks, good to know, do you have a specific nightly build you're comfortable with?

When I had this problem (happened to me several times) I found out that the "big" corrupted files were in fact recording that stopped at the beggining that I had to stop by removing the battery. These files are actually almost empty but are reported with a wrong size on the CF card. May be wrong, but that is what I think.

Well, I have those types of corrupt files too sometimes, but this looks like a different kind of corrution. The camera never indicates a problem or crashes, can review shot using MLV_play but cannot copy to computer(see details above).

3/ I use MLV_Rec more because the interface is more usable IMO. The latest MLV Lite is mor usable though. I'd reccomend both other the old raw_rec as MLV files are much easier to handle ;)
I'll try MLV, thanks!

I usually update ML as soon as I see an update available.
In the newer builds, both MLV_Lite (the old raw_rec updated) and MLV_rec record MLV files (can someone correct me if I'm wrong ?)
So no worries about that.

As there is development about new crop modes / lossless compression / 10/12bit recording I have to recommend you to update frequently ;)

Some time ago I played around with an dual iso video branch, that is supposed to work on the 50D and the 5D Mark II. I don't know why but it does not work on my 50D so far.
https://bitbucket.org/tecgen/magic-lantern/branch/5D2-50D-dualiso-video#diff

The good news is, I am able to record dual iso RAW video by changing the CMOS[0] manually to a value of 8, 18 or 28. (See also my post in the dual iso for 5D2 thread http://www.magiclantern.fm/forum/index.php?topic=16854.msg171694#msg171694)

Here you can find a MLV of an 50D dual iso RAW video and a dual iso DNG file that was created by MLVFS.
https://www.dropbox.com/sh/w2wemk17d5x95fu/AAAosfOCYFDQM4SPvoL4WHuda?dl=0

Can anyone help us to put these things together? It seams simple to get dual iso RAW video working even on the good old 50D.

I'd like to help on this subject. I had my VM ready for compiling and I'd like to try tweaking registers. But I have a problem.
When I try to load the ADTG_GUI module, the camera doesn't manage to load the modules. Am I missing something ?
