Thank you guys for your fast response

@Licaon_Kter:
Ok, sorry for the confusion, I meant raw video editing. So if I understand correctly, recording raw video with Canon 50D does NOT produce a sequence of raw images, but a single file (or several files, as I read that sometimes you have to join them), from which raw images have to be extracted for processing?
Can't check it myself now, because I am still waiting for a fast card to arrive...
@dmilligan:
Which better than DPP free soft would you suggest?
I have Win 7 64 bit, Intel i5-3570K, 8GB RAM, no GPU (Intel HD Graphkics 4000 integrated in CPU) - Resolve will not work, because HD 4000 is not compatible

I tried VirtualDub and I am not impressed with color correction plug-ins I found, not to mention that most of them work only with 32 bit version of VD.
The only paid soft I have is Adobe Elements 6 with the latest COMPATIBLE ACR plug-in. I like it, but it seems that ACR allows only up to 200 raw files to load at the same time, so I can perform batch processing only on 200
