Questions and Assumptions
- What is your definition of DVD quality? By definition: Re-sampling the image with any product will reduce the quality.
- What degradation of network performance are you willing to tolerate?
- I assume you want the PCs to watch the same feed with no ability for anybody to pause the feed.
- I assume you are talking DVD not blue ray.
I recommend
- Use VLC to stream at different audio and video bit rates.
- Determine the lowest rate that is acceptable to you
- Set up a VLC Multicast test and determine how it works for you.
- Review the math against theoretical limits.
The math
VLC Player tells me it takes about 6MB to stream from one of my DVDs. Would you accept a 6-10mb hit on your wireless network? You might want to do some research and see how much bandwidth you really need to have. I routinely download files at 6mb-8mb transfer range. My wife can still use the internet but it is slower. I suspect you won't need 6mb but that is the reason for the previous test.
Note: When several users are involved you can't get 54mb out of a 54mb wireless network due to collisions.

Good luck.
