In mini EPG, you do have genre wise channel listing and i feel that is more better. In d2h the hardware is not able to handle the software, the UI is good but the hardware is not that great and leads to hanging issue,lags and that puts off an user. i have used RDTV that has pathetic UI but atleast its hardware is better compared to d2h.
If you press the OK button in TS remote, mini EPG pops up, select green or other button to choose channel from there and no need to go to organizer.
