What Is Doom9's Forum and What Can You Find There?
Doom9's Forum (forum.doom9.org) is a long-running discussion board for DVD conversion and digital video work. Its own description calls it "THE in-place to be for everyone interested in DVD conversion," and the board's keyword set — video, DVD, conversion, MPEG-2, MPEG-4, DivX, Xvid, AviSynth — maps closely to the sections you'll actually find inside. If you need help ripping a disc, encoding video or audio, handling subtitles, or scripting with AviSynth, this is the kind of community where those questions get answered. It is a forum, not a download site or a product, so what you get is threads: tools, guides, and troubleshooting discussion contributed by members.
What the forum covers
The board is organized into categories, and the section names tell you most of what you need to know:
| Area | Sections | What they're for |
|---|---|---|
| General | Announcements and Chat, News, Forum / Site Suggestions & Help | Off-topic chat, digital video news, and feedback about the site itself |
| Decrypting | Decrypting, Newbies | Getting files off (HD) DVD / Blu-ray discs onto a hard disk; beginner questions about DVD ripping |
| Video tools | DVD2AVI / DGIndex | Anything using DVD2AVI or DGIndex |
| Audio | Audio encoding | Audio decoding and encoding |
| Subtitles | Subtitles | Making, editing, and displaying subtitles |
| Other platforms | Linux, Mac OS X, & Co | DVD backups on Unix-like systems such as Linux and OS X |
| Capturing and editing | Avisynth Usage | Capturing (HD) TV and video, cutting existing sources, and everything about using AviSynth |
The activity numbers give a sense of where the depth is. Avisynth Usage is the largest section by far, with over 14,000 threads and more than a million posts. Newbies and Audio encoding are also heavily used. So if your question is about scripting a video filter chain, you're in the busiest part of the forum; if it's about a specific ripping tool, the Decrypting section is the place to search first.
How to start using it
The forum's own welcome text lays out the expected first steps:
- Read the forum rules before posting. The welcome message states that by posting you agree to abide by them.
- Check the FAQ. First-time visitors are pointed to the FAQ link at the top of the page.
- Register if you need to post. The welcome text says you may have to register before you can post, and directs you to the register link to proceed.
- Pick the section that matches your topic, then start a new thread or reply within it.
A practical habit before posting: search the section first. With tens of thousands of threads in areas like Newbies and Avisynth Usage, many common problems have already been discussed, and the answer may be sitting in an existing thread.
What to expect as a newcomer
Two things are worth knowing up front. First, registration is part of the flow — the forum explicitly says you may have to register before posting, so don't expect to drop a question anonymously. Second, the site is a community rather than a curated knowledge base: answers come from other members, quality varies by thread, and the most reliable material tends to be in long-running tool threads and the sections with active moderators. The board lists moderators for several sections, which is a reasonable signal of where discussion is kept on track.
If your interest is DVD conversion, video encoding, or AviSynth scripting, the forum is worth browsing even before you register — the section list alone is a useful map of the tools and topics involved. Start with the rules and FAQ, search the section closest to your problem, and register when you're ready to ask.
