Sorry for not getting back sooner, but, I managed to sort it......
You have to use cross epg and the script in the rytec file (mentioned above server by others) needed altered very slightly to make it work, I have uploaded working altered file since a lot of other members have viewed this subject, perhaps it will be included in next BH image update/release.
Download and unzip the file below, replace existing in usr/crossepg/providers using ftp, restart box, configure in cross epg to select provider (above), then download epg (can take a little while, but be patient it is worth it).
Btw I did try the OBH image and didn't like it at all, maybe some day it will be as user friendly as the original BH image? now very happy as I am sure a lot of others will be.
I hope this helps.
