Can I ask where?
Through kabayancentral.com
It is a burned copy only, but from authentic source (so no copyright infringements). It is a fairly good print as well, there must be some degree of restoration done. Other available titles from Mike De Leon/Cinema Artist Philippines/LVN (as currently advertised) include A Portrait of the Artist as Filipino, Bayaning Third World, Southern Winds, and Bilanggo Sa Dilim. Maynila sa mga Kuko ng Liwanag was available at one point.
I hope this helps.
