018: The Digital Bits.
If you're in the low-budget horror (or sci-fi or action) movie business, you're in the DVD business. Unless you have a time machine that can take you back to an era when low-budget flicks were a staple of drive-in and grindhouse theaters.
My favorite source for DVD info is TheDigitalBits.com. The site's writers do a good job of covering industry news and trends (their coverage of the current high def disc format war (HD DVD vs. Blu-Ray) is really heating up lately), plus they crank out plenty of disc reviews (and previews) for folks more interested in watching movies than making them.
