Oaf may be right, you may want to try an "A" stock 950. I have not had a single problem with the switching of any input/output on my 950. However, I can understand your frustration. Outlaw was so quick to send you another unit that you were impressed. It would have been better if the video inputs/outputs could have been checked before sending you another unit. Sure this would have caused a delay but you would have been another satisfied customer instead of one that is contemplating the purchase of a "clone." Obviously Outlaw will replace this defective 950 again, but the time and cost spent sending you replacement units far outweighs the time and cost of a QC check before sending out the unit in the first place. Stay with us, don't let the sheriff catch you, an outlaw behind bars is a sad sight. Outlaw will make it right.
