Dr. DivX 2.0 is available for free at http://labs.divx.com/DrDivX
The DivX bundle currently available for download from http://www.divx.com/divx/
is different. The bundle includes
- DivX "Community" Codec 6.4
- DivX "Pro" Codec 6.4
- DivX Player 6.4
- DivX Web Player 1.2.0
- DivX Converter 6.2
The Players are free. The Converter and the Pro Codec are trial versions. You'll have to pay to keep using them past 15 days. However, you can use Dr. DivX instead of Converter and you can use the Community Codec instead of Pro for as long as you'd like.
If you're doing a lot of encoding, I'd recommend buying the Pro codec. It's faster and offers higher quality than the Community codec. It's faster because it can take advantage of hyperthreaded and dual core processors while the Community codec doesn't. The Pro codec also offers higher quality settings that are unavailable on the Community version.
While the Converter is simple to use, it doesn't offer near the flexibility of Dr. DivX. The Doctor can seem complicated at first, but it really produces nice results. As mentioned earlier, you can use other programs like VirtualDub with the DivX codecs (both Pro and Community). I've tried a few. In my experience Dr. DivX is the easiest way to get the most out of the DivX codec.
I've tried other codecs like XviD, H.264, and Windows Media. For me, it comes down to the tools. Dr. DivX with the Pro codec is the fastest, easiest, best quality combination I've found despite the fact that H.264 is theoretically a better codec. I don't use the highest bitrates or the insane quality settings but I still get videos that look fantastic on my 50" HDTV. For example, a 42 minute episode of Lost looks very nice at 700 kbps, 720x400 resolution, yet weighs in at only 272 MB.
