Try using Xmltv importer and not crossEpg. If you get it all set up correctly it will work perfect. I've got 3 boxes running openvix (on 1 box) and openATV (2 boxes) and I don't have any problems with my EPG using Xmltv importer. Also make sure you use a decent flash drive or SD card (or HDD ) to store the EPG on. I'm sure people experience minor issues using unbranded storage devices.
