Slingbox HD and 522

[Xinstaller]

I was curious if anybody is using this setup. I have both 622 and 522 dvr's and I have been wanting to get a slingbox for some time now but I would have to hook it up to the 522 for the time being. My contract with dish has expired for some time now and I am a month to month customer. I am waiting for the 922 to come out but I kindof need the sling feature for the holidays as my parents and inlaws have basic Dish service. Thanks
