I'm sorry but thus post is pure nonsense - I have > 100MB big EPG database with 30 days which is PEANUTS for a box with 2GB Mainmemory - I still have almost 1GB free memory after starting enigma2
So the only sweat is on the competitors or the so called great and innovative Open Source developers who are still enjpoying EPG stuffed into a >10 year old binary file solution.
