Gregfisk,
Your timing to post your question on this is MAGICAL for me. I only just last night tried (in vain) to use screen share from my Mini to my iPad. I hadn't realized till now that an additional app was required.
Since our move to Taiwan, I have suffered with not-quite-redbook for most of my music because my audio and Mac Mini are in separate rooms. With this feature, I can relocate the Mini anytime I gotta have red book or better. [I'm betting folks will scratch their heads at that statement. My CDs are all back in Oregon and there's no CD player in the system. My SBT is streaming 320kbs music, and keeps having wifi connection issues with my Mini - mostly unconnected. I can't figure out the issue behind this. I can play music from my iPhone or iPad via Bluetooth, but that sucks the power out of my somewhat underpowered amp.] This was supposed to be a worry- and hassle-free vacation/2nd home system.
Thanks!
Michael
