i've noticed this lately as well, after the initial signal quality updates a couple of months back everything worked great for a while, but in the last month or so i'm seeing some corruption errors as well. same card, same machine, same signal theoretically. it seems to affect all channels but it's still much better than before the signal quality updates.
