You do realize you lose any AUDIO by having DVI?
Your only audio output is likely the headphone jack.
You might wish to consider a different tactic such as the WDTV LIVE which can either STREAM your video from the laptop, or you can copy the video to a USB thumb drive or laptop drive.

There are similar products but I haven't used those.
I know the WD played everything I can think of including:
- MKV/MOV etc.
- Vorbis/AAC/MP3 etc.
- *even ISO images of DVD or BluRay!
- Netflix..
I think you can find them for as little as $80.
