There is no OpenCL 2.0. See the official site, it’s only OpenCL 1.1.
The Quadro FX3800 *should* be able to run VP11. I’ll throw in the card and report back. It’s GT2xx based, which on the Sony website says is supported. I have just tried out a FX2700M, and it does GPU accelerate the MainConcept AVC renderer via CUDA, but not the playback part (which is done via OpenCL, from what I understand). A Quadro 5000 worked fine with MainConcept AVC and the video playback. What does not seem to work is using the SonyAVC codec for say 720p for youtube ;-(
A FX4600 is a far as I recall based upon a G72GL. That is pretty much hopeless for CUDA/OpenCL.

Two late suggestions.
One on HP laptop my wife owned after a while there would be dust accumulating between the heat pipe and the fan module. After a while there would be a solid layer that did prevent proper airflow and hence lead to overheating. Since having tracked that one down I peridically clean out all our laptops …
Another thing I had been running against is overheating of the GPU. Either my power supply (120W) was too small, or there was an issue with the GPU’s power management, but essentially after 5 minutes of rendering the system just went black. Switching to CPU only rendering did help.
Another small hint. Whenever I do something where I know the CPU/GPU are on a very high load, I put a pair of wine corks under the back of the laptop, so that the airflow to and from the fan maximized. Since the box is sitting there anyway and rendering it doesn’t hurt.

I bought the one off B&H. It did come with DVD Architect Pro. Maybe the Adorama version is different.

I am running Win7 PRO, my wife Win7 Home Premium. The only real difference I could see was the XP Mode via the Virtual Machine. I needed that a few times for ancient games my younger kiddos like to play. Other than this I have not really found a difference worth a cent.

Here is the real example. It’s a screen that gives some stats of volleyball players in the preceeding video. Something like:
Nancy Sue 5'10" OH/Setter 2014
Giggly Girl 5'8" Setter 2013
Evil Spiker 6'2" Middle 2013
So, a very simple table, 4 columns. Can be done trivially if you have tab-stops. (cannot really show this here, as this text widget has the same issue ;-))
Yes, I can do this in Photoshop/Illustrator, but I was looking for a simple way to do this withing Vegas quickly.

I had looking into that issue before as well, and went with the GoPro HD 960 instead.
The GoPro comes with the best selection of mounts. Whether on my roadbike, or my longboard, or helmet … well there is a suitable mount or mount combination out there. Lot’s of things to play with.
For youtube 720p is good enough. So that turns then out to $350 for the HD170 vs $180 for the GoPro 960.
I do like the replaceable housing with the GoPro. If you crash that thing, just get a new housing for $40 and be done with it.

One thing for youtubes is that the AVC renderer does 29.970fps. I sometimes get material with real 30fps. In that case the Sony AVC codec is not usable as it crashes for me when I try to match the frame rate. The MainConcept codec does allow to do that.
Why does it make a difference ? If you have real 30fps source material and convert that to 29.970fps then either you start interpolating frames, or if you disable that, you get some stuttering (barely visible, but still). I found this especially unpleasant if the source material contained considerable movement …

[John Rofrano] ” [Thomas Roell] “(3) This is the more tricky on. Is there an advantage/disadvantage to having your video files on a separate partition, but on the same drive ?”
No, really no advantage at all. The whole idea of having your files on a separate physical drive is to reduce drive head contention since each drive has it’s own heads. Having two partitions on the same physical drive can actually make this worse because there is only one set of heads and they must seek across two partitions.”
Hmmm … I was more thinking along the line of disabling system restore and using a different cluster size. The head contention is probably not a real problem on a single driver system, given how often system processes do something behind your back and will move that heads no matter whether there is a single partition or multiple partitions. Then again, this is just a guess …

Beeing a Newbee here, I got also a few questions for Vegas Pro 10 and setting it up on a Laptop.
For reference, I got a Sony VAIO F, 1080p display, Core i7, 8GB ram, 500GB HD, NVIDIA 425M (since I work for NVIDIA, I couldn’t get ATI ;-)). The system is running Windows 7.
Now to the specifics:
(1) The GPU rendering on a 425M sucks. Just used straight transcoding in the AVC codec. Any ideas ? As far as I understand it, the 425M has 96 cuda cores, and should have about 215 GFLOPs, while the Core i7 should max out at around 40 GFLOPs.
(2) I am seeing a lot of disk activity eaten up by the SearchIndexer. Is there a way to avoid that other than to nuke the Windows Search to begin with ? (yes, I excluded the directories where the video files live).
(3) This is the more tricky on. Is there an advantage/disadvantage to having your video files on a separate partition, but on the same drive ?
