Well gnat posted this info first but as a follow up the rumor is that its based on the Sigma EM8622L running at 200Mhz and if so it should be able to support the following:

Video Decoding
• MPEG-4.10 (H.264) BP@L3, MP@L4.0 and HP@L4.0
• SMPTE 421M (VC-1) MP@HL and AP@L3
• WMV9 MP@HL
• MPEG-2 MP@HL
• MPEG-4.2 ASP@L5 (720p, without GMC)

Advanced Video Processing
• 32-bit OSD
• 2D graphics accelerator with scaling
• Motion adaptive deinterlacing
• Adaptive flicker filtering
• Programmable up/downscaling
• Prioritized 5-plane alpha mixing

Here is a picture:

Any idea if the new Sigma chip fixes the braindead fast forward and rewind setup on the DSM-520?

In case folks aren't familiar, the DSM520 has two mutually exclusive FF/REW modes. One lets you punch in the time in the video you want to jump to and the other only fast forwards or rewinds at about 2X. This is THE major usability problem with the device, in my opinion.

I'm looking forward to seeing the 750 as well. As for the FF/RW functionality on the 520, the 510 must be is different. There are 2x, 4x, 8x, 25x, 50x, 100x speeds which actually work fine with 720p files although don't seem to work with 1080i files on my system.

H.264 was the primary reason I returned the 520. Can't wait for this one to try out on my ripped library of H.264 content :-) Now, if it also ends up supporting anamorphic matroska files with H.264 video streams and AC3/DTS audio streams, life will be good

Does anyone know if you can create an anamorphic MP4 file? If so, then the MP4/AAC/H.264 might be good enough for me.

To my knowledge, nowhere. There is another player coming out supposedly at the end of the month or in May (Tvico 4100sh) which has a "better" chipset in it, which should supposedly transfer HD files faster. Now of course this other unit doesn't have the draft n wireless capabilities, but if you're on a wired network then you might want to consider it-it is available for pre-order at digitalconnection.com for around $320.

I was hoping that someone may have some info on the DSM-750.

I have just about given up on Dlink but I have hopes for what they say it will do. But then again, their lack of answering emails and when they do they do respond to an email, they don't answer the questions in the email.

Will there ever be one in existence.I know patience is a virtue but they said early second quarter..if they are late on the release.what about the FW updates???

Just FYI, their competitors have their boxes out in the market now and are going through the usual early firmware revisions for bug fixing. Both the TViX 4100/5100 and the Netgear EVA 8000 are available. The TViX is back-ordered at digitalconnection, but the EVA 8000 is in-stock at Amazon.com.

Thanks for the reply..watched the Netgear go down in smoke.been watching the TViX and it is close to what I want (need VC-1) but the Dlink is supposed to do it alljust getting pi$$ed that we have seen nothing yet and they will not answer any questions in emails.

Hey, would like to explore your comment about the Netgear "going down in smoke". I am considering whether to go Netgear or TViX. I have a TViX but have not been able to use it at all because their Wi-Fi is broken right now. That is frustrating me! What about the Netgear does the TViX outdo?

This is more a quality of the client firmware than the chipset. For example, the DSM-510 uses the DiXiM Media Client by DigiOn, which has a much nicer user interface and no problems with exclusive modes for FF/REW and jump.

That said, I haven't seen the DSM-750 user interface, so I don't know who's client firmware they're using. Has anyone?

still waiting. the silence on this product really sucks. Fortunately, thanks to updates from Sony, I can use my PS3 for streaming my h.264 content, but their user interface isn't the greatest to navigate through hundreds of files. Plus, I don't want to have to buy another ps3 to stream to my other tv's.

It would be really great if DLINK actually listened to current users of the 320 and 520 as what we would like to see in this new unit BEFORE it is released. Unfortnately I suspect it will once again just miss the mark at being 'THE" unit to have. I have been amazed over the years at just how out of touch DLINK seems to be in regards to this machines and their potential. I have my fingers crossed that they have learned from past issues.... cuz I sure would like to have one (IF it works - reliably with solid (TESTED) firmware). Not bashing DLINK, just tired of their sub-par programming efforts to date. Owner of two 320's and one 520..... looking to add a 750.... maybe!

My guess is that the firmware for the 520 is a subset of the 750 firmware with some changes. If correct, I don't expect to see the 750 until another update of the 520 firmware appears because V1.04 still doesn't work with other uPnP servers. Before buying another DLink product, consider the Netgear EV 8K. Netgear is supporting an active forum with frequent beta updates unlike DLink.

You have to remember that D-Link has relatively little to do with the overall user interface and feature set of these products. Aside from the initial decisions to select reference hardware (based on a Sigma Designs development kit) and client firmware, they're basically just a support organization that does limited triage and then passes a prioritized list of issues to 3rd parties. While D-Link isn't entirely blameless for the DSM-520 firmware debacle, we should really be directing our wrath at REDsonic, the actual client firmware vendor for the DSM-320 and DSM-520.

Probably the best thing we could do for the DSM-750 to prevent this from happening again is to start a write-in campaign encouraging D-Link to stick with DigiOn's DiXiM client firmware (used in the DSM-510) for all new product releases. While it's got its own set of problems (mainly dealing with intentially crippling support for MPEG-4 ASP video with DivX FourCC codes), the user interface is light years ahead of REDsonic and what I've seen from Syabas (used in the Netgear EVA-8000).

Of course, REDsonic's Web site has been down for a while, so maybe they're out of business. Actually, that might explain a lot.

By pure happenstance, I got a quick peek at a DSM-750 prototype yesterday. There was nothing confirming this in the About box, but it looked to me like the firmware is based on the old REDsonic code base used in the DSM-320 and DSM-520. The screen layouts essentially look the same with updated graphics that give it more of a Windows Media Center feel. Unfortunately, I didn't have access to a UPnP server with videos, so I wasn't able to determine if the dreaded Seek vs. Skip exclusive modes still exist or if they now support faster seek speeds and resuming playback.

Probably the biggest surprise was that it includes v2 of the Media Center Extender firmware (codenamed Pika), allowing it to run Media Center remotely from a Vista Home Premium or Vista Ultimate box just like the Xbox360. I'm personally not a big fan of MCX because it requires hosting a terminal server session on your PC for each connected device, which commits significantly more resources and processing power than serving a UPnP media session. In addition, the v1 MCX device I had wouldn't play Xvid/DivX videos, requiring you to transcode them to WMVs before being able to play them back.

Overall, I'd say I was pretty disappointed. The user interface on my DSM-510 is much nicer and with all the issues I've had with the DSM-520, I would have much preferred them using DigiOn's firmware for the DSM-750. I guess at this point I'll just have to hope that someday soon they'll update the DSM-510 with support for VC-1, H.264 and 802.11n.

I don't know if it is a good idea to judge a protype product. In the company I work for we always have prototypes flying around that aren't ready for prime time. In many cases the user interface may come from a different product just to 'try it out' and prove various functions work while the final interface is being developed. In many cases the user interface isn't what will be used in the final product. Even if the user interface on the 750 has the same look as the 520 I don't think I would use this as a determination that the product is not worthy of purchase.

My opinion would be that I would not make judgements on a product until it was in full production.

So I am a happy camper with the DSM-520 except for the FF-Seek issue and the lack of H.264 support. I have been waiting for the DSM-750, but see that Apple TV is already available with H.264 support. I have encoded all of my video library into H.264 format using NERO Digital and have been completely satisfied with the converting results. However, I have been using the Nero Mediahome uPnP server (which changes from release to release - that is whether it works or not) and unfortunately have to have it convert on the fly to MPEG2. I would like to not have to convert at all, but be able to display the H.264 files in native format - thus my interest in the DSM-750 and the fact that I refuse to by Apple products. I've tried TVersity and Twonkymedia and neither works any better than Nero. How hard can it be to produce a media player that supports H.264???

AppleTV and DSM-750 (or it's already released competitors) are not comparable.

AppleTV is 5Mpbs rate limited and 720p limited.

It's "hd ready" not "full hd". It cannot do TS/MKV or high-bitrates. It understands nothing of VC1.

It's really a very crippled hw front-end for Apple's video iTunes sales.

Hardly a welcome HD player.

But back to DSM-750...

It was rumoured to be released in September (2007).

I wonder what is happening?

I got a peek at a later firmware revision of the DSM-750 a couple of weeks ago, and now have to admit that fccgrant was right: It's unfair to judge a product based on pre-production firmware releases. My assumption was that the firmware would be close to final, given the expected release date at the time. Well, they were obviously quite a ways from a release candidate, and the firmware has seen some significant improvements since then. It's definitely not the DigiOn firmware used in the DSM-510, but it's already significantly better than the DSM-520's (which isn't saying a lot, I suppose). The Pika firmware actually presents the best user interface of all, and I have to admit that Media Center Extenders are much more attractive with DivX/XviD support now. There's just the additional cost of the OS and the higher CPU and resource load on the PC to consider.

Engadget has some additional info on these Pika extenders, including the DMS-750 :

A couple of semi-off topic questions:

Aren't the 510 and 320 different beasts than the 520? Isn't the 520 a full on unit, whereas the others rely on the server to decode at least some codecs? Would the new unit be reliant on a server?

Is there any player that doesn't suck fast forwarding video files without chapter breaks? I have the buffalo, it goes up to 4x ff, but if you're into the movie, that's not nearly fast enough. :/
