What should I look for?
If you have any real time malicious software installed/running what is
it: Norton, McAfee, ZoneAlarm, etc.
What software package is playing the video?
Please provide additional information about your system:
Click Start, Run and in the box enter:
msinfo32
Click OK, and when the System Summary info appears, click Edit, Select
All, Copy and then paste
the information back here.
There will be some personal information (like System Name and User
Name), and whatever appears to
be private information to you, just delete it from the pasted
information.
This will minimize back and forth Q&A and eliminate guesswork.
Perform some scans for malicious software:
Download, install, update and do a full scan with these free malware
detection programs:
Malwarebytes (MBAM): http://malwarebytes.org/
SUPERAntiSpyware: (SAS): http://www.superantispyware.com/
They can be uninstalled later if desired.
If you are using IDE drives, use Device Manager to verify the transfer
mode of the IDE channels is set
to some kind of DMA mode (depends on your hardware) and not the slower
PIO mode.
PIO is the slowest, DMA is the fastest.
This is easy to check and generally easy to fix and the mode would not
have changed by itself,
so if it has changed to PIO, change it to DMA and then figure out why
it changed and fix it.
To launch the Device Manger console, click Start, Run and in the box
enter:
%SystemRoot%\system32\devmgmt.msc
Click OK.
Expand the IDE/ATA controller section to see your IDE channels. Right
click each, choose Properties,
and for each channel that has an Advanced Settings tab, determine the
Transfer Mode. There are
usually 4 channels to check in a desktop, maybe fewer for laptops.
The fastest selection will be some DMA selection (usually: DMA if
available). If it is PIO, change it
to DMA.
If you are not sure about what you see post back for help and advice..
Follow this up with a reboot to make sure any changes stick.

Download speed of AT&T DSL was 720 Kbps
Upload speed was 162 Kbps
(did I hear an uh..oh?)
I did a simple test here. I went towww.cnn.comandplayed some of their
videos. I used the Task Manager networking tab, to watch the download
speed. The download runs as fast as my link to the Internet will go.
The download takes about 1/5th of the total time of the video playback.
Since my download speed is capped at about 500KB/sec, that means the
video must be playing (consuming data) at about 100KB/sec or 800 kilobits/sec.
That is just a rough figure, comparing the length of the play bar and
download bar on the video player window (Adobe Flash).
Maybe there is a better way to determine the bitrate of the video,
but I haven't figured out how to check.
Now, compared to your download speed test results, that is very close.
That means there is a danger that the download can't keep up with the
playback data rate, so buffering will be required. At least for
the videos I tested on CNN.
Paul
A lot has happened since my last post.
Disabling the security software programs one at a time did not change
the problem.
As per your suggestion I called AT&T Tech Support to ask for help with
a slow DSL.
After a few checks they determined my system met the range appropriate
for DSL Light which is 780kbps.
Various speed checks gave various results and the lowest was on AT&T's
speed check of DL 435kbps and UL 53.56kbps.
Tech Support offered to connect me to Sales for a possible discount on
a faster speed. Well their offer for 1.5Mbps was $7 higher than a cold
quote over the phone the day before. End of AT&T.
Comcast charges $28.95 for 1.0Mbps which is likely more reliable than
the AT&T. Still far from my needs.
There is an open wifi in my condo building and it seems to be on all
the time. So I bought a $39 D-Link connector and now use wireless unti
further notice. My Dl is 3Mbps and UL is 547kbps. Needless to say
videos are flying fast.
Folks I am 82 yrs old and on Social Security limits so when a saving
arrives it must be taken.
I want to thank all for the generous help and thoughtful attention to
this problem.
You guys are good!
Bill
That's a good one!
