When I try to use AGP 8X the computer crashes constantly, but I was able to try a HD video and didn’t see really any change in performance. I have fast write enabled in BIOS, but every time I try to set fast write to enabled in SMARTGART settings in the Ati control panel, the next time the computer starts it has gone back to disabled.

Make sure it's enabled, once it is it will work perfectly @ 30fps. Update your bios, etc.

Hi Matrix, my motherboard is about 3 years old and the last time the vender provides bios update was 1.5 year ago...
Also, chipset refering to that of the graphic card? They don't have update for it's bios ...

Keep hearing people talking about updating the bios, also heard that it is quite a risky act. How do I do it safely? Thanks.

Default Bus Speed

I would register the two activeX controls and make sure you click on the license generator. This will get rid of the ActiveX security message. I find that it didn't play in 3/4 of all the PCs I tried in Fry's where I wanted to check LCD screens. I won't play in my Office PC (2.4 gig but only 256 M memory and 400 MHz bus). However it plays well on a Celeron D (2.66 MHz) with 512 Meg of memory using only the motherboards built in Intel Graphics. It might be that bus speed is almost as important as CPU speed once you have at least 512M of RAM.

I find that the video stutters and runs at only half of the frame rate it is supposed to. Does anyone here know what system requirements are necessary for smooth playback of 1080p?

Microsoft recommends:

Minimum Configuration (to play 720p video)

Windows XP
Windows Media Player 9 Series
2.4 GHz processor or equivalent
384 MB of RAM
64 MB video card
DVD drive
1024 x 768 screen resolution
16-bit sound card
Speakers

Optimum Configuration (to play 1080p video with 5.1 surround sound)

Windows XP
Windows Media Player 9 Series
3.0 GHz processor or equivalent
512 MB of RAM
128 MB video card
1920 x 1440 screen resolution
DirectX 9.0
DVD drive
24-bit 96 kHz multichannel sound card
5.1 surround sound speaker system

For either configuration, an AGP4x-based NVIDIA or ATI video adapter card with the most recent OEM driver updates is also recommended.


My system has a P4 2.8 GHz processor, but exceeds all other requirements. Would the extra 200 MHz make such a big difference? I also have a Radeon 9800 Pro 128 MB graphics card running at AGP 4x with Fast Write disabled (because of incompatibility with the motherboard). Would Fast Write make a difference?

BTW, I am also having a problem opening the Coral Reef Adventure disc menu – it comes up with: “Your current security settings prohibit running ActiveX controls on this page. As a result, the page may not display correctly.” I have tried lowering my security settings in Internet Explorer to the lowest possible, but still get the same message.

I would appreciate any help with either of these issues.

I bet the Intel inbuilt graphics card allows Fast Writes on your Celeron D computer with 512MB RAM. I have spent weeks researching the importance of Fast Writes and feel I’ve come to the conclusion that without them, it’s almost impossible to play 1080p videos without frames being skipped. This forum had discussion about it, here’s a post from it:

can someone help me out here?

Here is a screenshot of the WMP HD rating program.

Apparently my processor (2.2Ghz AthlonXP) and my FSB and memory subsystems are better than average in both the 720P and 1080p. However, my video subsystem (9700Pro Cat 4.7) is below average in both. WTF?

Edit; NVM! I just read up a bit, realized that Fastwrites was off, turned them on, and bam! Now I am above the requirements in both, all green.
I would say bus speed is also very important, when I run the WMVHD performance tool my bus speed and main memory subsystems show green for both 720p and 1080p so I should be fine there. My video subsystem rating is way into the red for both, like the guy I mentioned above. I can't get Fast Writes enabled on my motherboard because of the graphics card being completely incompatible with the chipset, and am replacing it next week with one that will so 1080p will work properly.

Default Windows Media Player (WMP) is bloatware and inefficient

I have an Athlon XP 2400+ and Radeon 9800SE setup. With WMP I could not play any HD WMV files even 720p ones. I then discovered Video Lan Client (VLC) media player http://www.videolan.org/.

This media player plays all the 720p files perfectly, and I discovered it can play any media file as long as you got the CODEC, even DVDs. The other cool feature is it lets you stream what ever you are playing over your network to another VLC media player.

Probably the best thing about it is, it is totally free.

Explorer.exe seems to use the cpu excessively for a few minutes after playing them too.
I downloaded these and had problems as well. While they have MPG extensions, they appear not to be fully compatable MPEG files.

I use Ulead MSP editor, and have the HDV plug-in, which allows me to edit HD MPG files. I thought I might try to edit the files, and maybe help things. When I tried to bring the files into the editor, it informed me that it was not an MPG program file, and invoked a utility to convert it to MPG. This normally must be done with transport stream files (tp, ts, m2t, etc.) in order to edit them. It did NOT re-compress the files, as the conversion process is very fast. What confuses me is that the files appear not to be bona-fide transport stream files either. At any rate, the converted files play fine in my various players (Dvico, on-air, Elecard, VLC).

I then tried using VLC to convert the stream, which seems to also work.

1. Browse to open the downloaded file (NOT quick open)
2. Check "Stream Ourput", and open the "Settings..." box.
3. In the "Settings" box, check "file" and enter a file name (with MPG extension)
4. Select "MPG PS" as Encapsulation Method. (for MPEG program stream file)
5. Do NOT check any transcoding options.
6. Click "OK" in both boxes, and watch the slider bar move.
7. Try playing the new file (which is slightly smaller - indicating that the original file was more like a TS file.

Hope this is helpful.
