The DVD format allows up to 9.8Mbps, while HDTV requires 19.25Mbps for full- bandwidth transmission.
So how is it possible to get a great picture at only 8Mbps @1080p ? Must be quite the compression algorithm. Something must be lost right ?
There's no algorithm, god I wish there was!
DO NOT buy the DSM-520 if you plan on streaming DVD quality content. I have ripped all my DVD's to my hard drive using DVDShrink. Lower quality content that is 4:3 such as the episodes of "That 70's Show" and my wife's "Charmed" work great. However, when you try to play a higher resolution DVD video folder like ANY 16:9 movie, the screen will stutter and lose sound at some point in the movie. Most of my DVD movies run between 8 and 9.6Mbps, which come to find out this unit can not handle.
I have tried connecting through wireless G, wired through my gigabit home network, directly from my server to the unit, 2 FAT32 USB hard drives (both not found), and 1 NTFS USB hard drive (also not found). I got a replacement from D-Link thinking that it was defective, and have tried both 1.00 and 1.01 firmware versions.
Furthermore, this unit does not recognize DVD menus or chapters. Skipping forward takes you to the next VOB file, and is unable to "rewind" back to the previous VOB file. This unit will only play the "default" audio track in the movie, which means that some movies you get the Dolby 5.1 sound, some movies you get 2-channel, and some the directors commentary. There is NO way to switch the audio signal.
My only other option with this unit is to compress the DVD's I have to a different format (which some of you have suggested), but I have so many that it would take an extremely long time to do (and I like having the DVD's in folder available to burn quickly). I did try last night to compress Star Wars Episode III (using professional software) to a maximum of 7.5Mbps. Still, a little while into the movie it started stuttering and I lost the audio. Bummer
The support rep for D-Link knew nothing about the unit or limitations. So now, I will be selling my unit on eBay (as ZipZoomFly will not refund my money), and purchase a different unit. I have been looking at models such as the AVeL LinkPlayer2, but have not done any real research yet.Can anyone please recommend a networked media player (from personal experience) that will properly play DVD folders with the menus, chapters, and stream faster than this 8Mbps limit? Any help is greatly appreciated!
EDIT: I just looked and found the speadsheet in another topic, which helps a lot!
