MPEG-2 and AC3 Decoders:
Easy HDTV and Easy HDTV DVR requires an MPEG-2 video decoder, sometimes known as a DVD decoder and an AC3 Audio decoder.  Most HDTV tuners come with an MPEG-2 video decoder as part of their included software.  If your HDTV tuner did not come with an MPEG-2 video decoder or AC3 audio decoder, you will need to get one to run Easy HDTV or Easy HDTV DVR.  Here are some available MPEG-2 video and AC3 decoders:

Cyberlink PowerDVD SE

InterVideo DVD XPack

ffdshow (Free) It's AC3 audio decoder has a great "Normalize" feature for averaging out the loud commercials.

Dscaler 5.0.0.8 (Free) We don't recommend using the MPEG-2 decoder included in this package as it is software only and has some problems with dynamic video size changes, but the AC3 decoder can be used with Vista which includes an MPEG-2 decoder, but no AC3 decoder.
