If you happen to receive emails that your non machine readable passport is not valid, well you need to read this post because UI just read from GMA NEws.tv that it is still valid and you could use this as a travel document whereever you go. refer to this post

Filipinos can still use their old green or maroon non-machine-readable passports for foreign travel until their expiry.

This was clarified by Philippine Vice Consul to Dubai Edwin Mendoza in an interview with Khaleej Times after receiving queries from members of the Filipino community whose old green passports are valid beyond April 1, 2010.

The International Civil Aviation Organization (ICAO), of which the Philippines is a member, has mandated its member countries to issue at least Machine-Readable Passports (MRP) by April 2010.

A brown MRP has since been issued by the Philippine government, but existing green and maroon non-machine-readable passports are still in circulation and can still be used for travel.

I own the green passport which are not machine readable, but I am still using it. In fact I just travel to Dubai about 2 weeks ago and all goes fine.
