Hi bothfly, make sure that your network at home meets the minimum requirements for the Ipad player so you won't have issues using the HQ option.
From the Link above you can find the network requirements, I added them here too.
"Adds High Quality (HQ) streaming. To stream in High Quality (HQ) mode outside your home, you need at least 800 kbps of bandwidth from your Slingbox to your iPhone when using a Wi-Fi connection, and at least 500 kbps with a 3G connection. To see available bandwidth within SlingPlayer Mobile for iPhone, tap the SQ button, then the Options button. The current bandwidth displays in the lower left corner. You can test your home upload speed by using a web site such as www.speedtest.net on your home computer; test download speed at your current location by using the free Speedtest iPhone app. The total bandwidth available to SlingPlayer Mobile for iPhone is limited to whichever is smaller: the upload speed, or the current download speed. If you don't have enough bandwidth for HQ mode, you can improve your viewing experience by pressing the SQ button to stream in Standard Quality."
