joker454 and NavNucST3, here are my preliminary findings so far:
Fast forwarding and rewinding large video over the network will "suspend" the player. You will most likely also see DLNA protocol error messages intermittently. If you wait long enough, it will come back (at least it did for me, but I really don't want to try these more than 2-3 times
). I tried it with TwonkyMedia 5.0 Server.
I suspect (but am not sure) this is due to deficiency in the DLNA server (Because it should look into the container and jump to the right "indices" as the video leaps forwards/backwards). If it doesn't do this fast enough, DLNA may time out. Microsoft may have added additional logic to uPnP to deal with this in its implementation.
In any case, my solution is to request the DLNA server to copy the video locally to play. Photos and music continue to be streamed from the DLNA server remotely. I then removed any HD or one-off videos from my PS3 HDD at my own leisure (since the server has a copy). Once the file is local, fast forward and rewind are extremely fast. In this way, I don't need a PC or RAID array (It's a cheap $200 box).
The main reason I do this though are:
(A) At home, I use a wireless LAN (77% signal strength). I tried viewing HD video over WiFi but the experience is not consistent. A lot of people will fall into this category in the near term.
(B) PS3 upscaling and other image enhancements. The videos on the PS3 HDD will be upscaled automatically (The player can employ better algorithms to treat the image if the file is local). My family loves this part since a lot of my home videos were taken on crappy cameras (or webcam my little boy took himself). They look great even in 1080p on my XBR today.
For me, the bad part is the folder organization. When I copy files from the server, it should automatically set the empty "Album Information" field to the server's folder name so that I can group them into the same folders as the server.
It seems that moving forward DLNA will introduce content synchronization capability (Many people probably don't have gigabit wired network at home):

Built on a foundation of technical work completed by the 240 member companies of DLNA, these Guideline additions offer:
* Photo, Video and Audio Synchronization providing automated synchronization of content across multiple devices.
* Menu Sharing allowing menu control of other networked devices.
* Wi-Fi Protected Setup making it easy for users to configure and add devices to a home Wi-Fi network protected with WPA2 security.
Inclusion of 802.11n and MoCA® connectivity standards in the Guidelines reinforce DLNA's commitment to work with other industry standard groups.
...and a more flexible playback infrastructure:

DLNA has added two new functions to its certification program. The expanded program includes “Play to” and “Print to” capabilities that allow connected devices to push photos, videos and audio from one device on a home network to another DLNA Certified device.
“Play to” and “Print to” functions let users send content to a rendering device such as a digital photo frame, TV or printer. This extends the traditional concept of players and servers to add a third device, digital media controller. Digital media controllers are useful for sending photos, video and audio to display devices which have inaccessible or no integrated controls. An example is a mobile handheld device or PC pushing content from a networked attached storage (NAS) server to a networked digital photo frame in another room using “Play to” functionality. “Print to” products let users send photos from a remote server to a printer.
When I have time, I will look into open source DLNA server to understand the HD fast forwarding problem. But for now, I am tied up by work and other personal projects
Where noise is concerned, my new 80 Gb PS3 is quiet. It's supposed to be quieter than the 60Gb anyway. I am sure the newer PS3 (with 65nm RSX) will be even more quiet. Don't think it's an issue for PS3 at all.
EDIT: I remember someone complained about slow thumbnail display on a PS3. At that time, I commented that the DLNA server should probably generate the thumbnail (instead of the PS3, because the latter can't write the generated thumbnails back to the DLNA server). It looks like MediaTomb is doing that now:
