Although for DMA access everything still has to go through the CPU because of the on-board memory controller. Obviously, this is different on Intel boards that can access memory directly from the northbridge - it's horses for courses as to which is the better solution, though.

Built in TDMS for dual link DVI / HDMI v1.3 with HDCP compatibility
versus the RS690's 64-bit DDR2 link through the CPU's memory controller

I've read elsewhere that the display controllers are single link only?
I don't understand this. Could you explain why RS690 doesn't get to use both of the memory channels in the memory controller (128bit).
Rumour has it Intel are working on a new driver for the G965 which should result in a large improvement in the current compatibility and performance issues. Could you confirm this?

At the moment, yours is the only comparison of the sort, and I'm very interested in the results of these tests.
The CryptoROMs are specific to each video output afaik, but every board I've seen bar the Asus has only one digital output so it's not mattered. Asus use a PCI-Express card for HDMI and HDTV out, which wasn't included in our initial package since it's a pre-production jobbie and we just literally got the board (no drivers even, and AMD doesn't have any on their site either ).
Don't understand question 2?! DVI and HDMI use internal TDMS, which are then disabled in the value model. You can change outputs in the ATI display driver.
Laptop: no idea, depends on the specific LCD controller used in the laptop. Not many people take apart review samples they get because it usually means irreversibly breaking the unit.
Unless your laptop has blu-ray, is HDCP needed?

If the cryptoroms are part of the chipset (and hence there are 2 sets) then I see no reason for limiting their use to one digital output at a time unless it's an issue of drivers.

Yeah as mentioned no one's been able to answer that question :? The reason I'm interested is because I'm wandering what my next laptop requires in order to play hi def dvd's should I choose to replace the optical drive it'll come with with a hidef one once the prices come down. I plan to buy a new laptop later this year so won't be able to afford one that comes with a hidef drive and so would need to buy one seperately further down the line. Essentially I want laptop that's ready in every way for next gen dvd's but without initially coming with the necessary optical drive. Hope that makes sense ;)

We've looked on the board but there's no external chip on either the Asus or MSI board we've got. Considering how long its take and it's A13 (?) rev silicon it should be inbuilt, however, an educated guess is that when licensing HDMI they also have to license HDCP at a cost of per implementation. So two = twice as much, adding an extra dollar to the price of the chipset and two dollars at least to the price of the end product since each individual company using has to have a separate license.
Two independent outputs, not necessarily digital. The only board ive seen with two digital outputs is the Asus and I dont know if they can be used together or are both HDCP compliant. It's something I will now be asking AMD in the coming week.
EDIT: Thinking about it, only one HDCP chip was included on the 7900-series that went out of their way to support it, despite all of them sporting two DVI ports.
If you dont buy a lappy with HDDVD/BRDVD built in, I'd guess that it's 99% likely it wont have HDCP unless you buy something that's G8x/R6x0 series derivative which has it natively. It's an expense ODMs wont bother including since 0.001% of laptop owners will replace their DVD drives for HD ones without replacing their whole laptops.
