ABS-CBN has been releasing some of its telenovelas/shows on DVD. So far, what I've seen in shops are:
Sa Piling Mo (Complete Series: 12-Disc Set - last two discs have not yet been released)
Gulong Ng Palad (Complete Series: 8-Disc Set, all available already)
Komiks Vols. 1-4 (Episodes Only: 2 Episodes per disc)
Maalaala Mo Kaya (Episodes Only - 2 packs available: The Anniversary Episode with Vilma Santos, the other with two other episodes from the show)
Pinoy Big Brother (Highlights Only, 6-Disc Set)
Pinoy Big Brother Celebrity Edition (Highlights Only, 2-Disc Set)
Pinoy Big Brother Teen Edition (Highlights Only, 2-Disc Set)
These are available at your local DVD shops/record bars nationwide. I think they sell for Php 150 per disc.
