The Raptor is freezing and locking up on encrypted VU Channels.

It's mainly Power VU channels. On 129.0W, I had to delete all TPs and rescan it as FTA only because every time I would try to delete a channel listed SVC_ 1,2,3 ect with Power VU encription it would lock the receiver up and the only way to recover was by killing the power using the rocker switch on the back.
This is not exclusive to 129.0W, I have had trouble on pretty much every satellite that I have scanned all channels and had to delete some that I knew would probably never be ITC.
Also noticed it is mainly the no name scrambled channels that cause the freeze-up. If a channels has a name like AMC E and W or TNT for examle, I can delete them with no problem.
