DD, early in this post, you said you had the camera only 30 days(which you should have contacted B&H immediately), now you call it a 3 month old camera, being at Canon for less than a month which means you are not telling the truth about it's actual age. Also, you should have copied your video onto a CD and not a CF card and they might have taken a look at it. You also didn't tell us which Canon repair facility you sent the 6D to. I hope you got your camera fixed or replaced for all you've been through, but your story doesn't jive.
hmm, I purchased the camera on Oct 24th and delivered by the end of Oct, when I contacted Canon, it was around Dec 8th, wasn't roughly a 30 days? yeah, 40 days exactly. But I passed the return window from B&H.
Now, it is 3 months old. I was saying the camera has been in their VA repair facility for almost a month for two repairs.
