Some weeks ago I wrote a email to Philips about the EPG Problem. I told them that maybe a solution would be to place a "dummy" EPG file on their website to suggest the iPronto that the EPG download was successful. Below you find the answer from Philips. So maybe there will be some hope for the future.
************************************* Thank you for contacting the prontoteam. We are very sorry to inform you that the EPG services is finished.
The EPG service is not available anymore so unsubscribe is also impossible.
We have discussed this in the team, and up to know we didn’t found a solution that fit the two of us.
We don’t have the resources and this is not planned to upgrade the firmware, the fastest solution would be to place a “dummy” like you mentioned.
We are taking this serious and hope that we can provide a solution to you problem in the near future.
In the mean time I would suggest to have some patience.
