Hi all - 1st post.
This is a great thread and is the most active and informative discussion on the Intel Little Falls 2 I've found. Great stuff.
I'm writing up a project on the Little Falls 2 mobo to show anyone how to build their own TV set-top box. Like many I was attracted by the low price, included Atom processor and S-Video / Composite video output. Like many I was disappointed to read about the problems many people have been having with the video.
I've got some experience with video and have some good news to share. It appears that RCA-style composite video is coming out of the S-Video connector, in full colour and in full composite video quality (see below).
What I suspect is the issue for many people is...
a) a PAL v NTSC issue; or
b) not having the right S-Video / RCA adapter
I don't yet know for certain about the PAL v NTSC aspect but unless this board is somehow auto-detecting which standard your TV uses - which I don't see how is possible, the board can only be outputting its video signal in one of those two formats. Normally this would be the prevailing format in the country where you are located. If people are buying this from online retailers overseas, then you might run into a problem.
However. It's also possible (and I intend to confirm this soon) that the motherboard is only shipping with NTSC output which would cause problems for people outside the USA who don't have a multi-sync PAL/NTSC TV. If you try to watch an NTSC signal on a PAL TV, it's possible it would come out in Black and White.
Since this is the same possible symptom as using the wrong adapter, it would be easy to confuse the two.
What I can tell you is that I am reliably getting good quality RCA composite video out of the D945GCLF2 using a simple in-line S-Video to RCA adapter (photo below). I'm using a UK sourced motherboard on a UK sourced Philips Ambilight TV which has both NTSC and PAL capability. Later this week I will try the board on a known PAL only TV via the RCA connector to determine if the board is in fact outputting NTSC.
Furthermore, running Ubuntu 9.04 I had no problem running two separate displays, one on the TV output and one on a VGA monitor. I was able to both 'mirror' display and 'extend desktop' display without difficulty. I had the TV output running at 832x624 and the monitor running at 1360x768 in 'extend desktop' mode. I tried other variations too. There was some sluggishness but it worked.
While I was doing research I did come across this S-Video / Composite adapter which may be worth trying for some people. I've ordered one to find out if it's any good and will let people know via this board.
Finally two other potentially interesting tidbits...
The video encoder on the motherboard is a Chrontel CH7201A chip. There's a Chrontel technical note (PDF) explaining why some PAL multisync TV's may have flickering issues with this board. I've had this problem myself watching Flash video and while this may be a red-herring (other reasons may be at play) it's worth noting.
The main Chrontel Technical Spec (PDF) talks about a video bypass mode which suggests that if you set your display resolution to 858x525 (NTSC mobo) or 864x625 (PAL mobo), the video information will pass through the Chrontel chip with only minor colour space processing and no scaling or scan conversion, leaving the original resolution intact. This should in theory give the best possible picture quality. I've not tried it myself (yet) as these are not default available resolutions in Ubuntu and I need to bone up a bit on the Ubuntu side of things.
Cheers and I look forward to contributing more.
