| Stream DVD quality, Yeah right DVD quality my ass, DVD is MPEG2, no way you can stream that. HD compression is MPEG4, and true HD which is 1485Mb/sec, I'd love to see that streamed.
I already dis-credit it for false advertising.

| Correct me if I am wrong, but DVD's have an average of about 3.5mbps (up to 9.8mbps according to the standard for variable bit rate DVDs).
Surely it can be compressed and streamed at a lower quality that wouldnt typically be detected as "flawed".
Also you are not representing the MPEGs properly. MPEG4 is the newer standard and allows for compression to go as low as 1.5mbps. HD may use that, but you can still compress the hell out of that just as much as anything else and still end up with crap at the end (see cable and sat versions of HD). |

| Yes you can recompress it, but then it's no longer DVD quality. Yeah i know it's a technical thing and the end user would probably never know the difference, but if you're advertising it as such, then that's what it should be.
It should be "equivalent DVD quality"

| The DVD quality you speak of is relevant. The mpeg 2 standard has varible bit rate and constant bit rate standards that DVDs fall into. Sure one movie may look better because they use a higher bit rate (constant or VBR) for video (i.e. super bit DVD's), but who is to say one is DVD quality while the other is not when they both meet the standards?
HD is not exclusive to mpeg 4 as the above poster implies either. MPEG is nothing more then a compression standard and HD uses mpeg 2 as well so in the end it comes down to the relevant quality we speak of. HD obviously has more informaton to feed the player so it has to run at a higher rate. Running HD over a 2mb or even 5mb line will obviously cause a lose in the quality. No one can argue with the fact that if you compress a picture you lose quality and there is simply no way around that at this time and probably never will be. One only needs to compare over the air HD to Satellite and Cable to see the difference that compression brings.
In the end it will depend on the user's connection. If they are able to stream high bit rates then they will have a better experience then someone that has to stream at a lower bit rate. Local high speed caching will help, but that will effect the user experience if they have to cache a 2 hour movie for 1 hour before watching it in all it's DVD glory. |
