Forgot about this post… sorry!
I went back to the store “pro video and tape” where I bought my EX1r and they have been trying to figure out the problem…
First they gave me a new sxs adapter, and everything worked fine until the last 10 minutes of recording time… It said “media error please reformat” or something similar I cant remember.
Then they tried a new card and adapter on another ex1r with firmware version 1.0 and everything worked perfect then they upgraded that firmware to 1.10 and are having the same problem as me.
Now they ordered a Sony sxs adapter and we will see how things turn out.
