WMM/DV capturing skips frames

I am a newbie on this digital video stuff. A few months ago, I started
converting DV tapes into digital using a JVC camera, Firewire cable and
Windows Movie Maker v2.1 on a lap-top Compaq Presario M2000/1.5Mhz/512Mb/60GB
with WXP Version 5.1.2600 Service Pack 2 Build 2600

At the beginning everything was fine and I made about 15 video clips with an
average of 20min-1.5hr length

The problem came up a couple of weeks ago when during capturing; the video
kind of freeze/skips a few frames every 2 or 3 seconds. The computer doesn’t
stop or hang and it still records all the way to the end. However, the
quality of the video motion is very poor as well as audio. It is not clear
and it looks/sounds like a poor VoIP call on a low bandwidth connection.

So far, I have taken the following steps without success:
- Disk clean up
- Disk defragmentation
- I cleaned out all the previous projects in WMM
- Obviously I have re-booted a hundred times
- Thinking that the problem might have been in the FW PC port, I swapped the
whole computer to a new one with the same specs only using the same hard
drive
- I tried using another program (ImageMixer with VCD v1.1) same problem
happened
- I installed Windows Media 9 Capture
- I have my C drive set to NTFS
- I have set the processor scheduling to background services and memory
usage to system cache
- Virtual memory is set to 3000MB initial and 4000MB maximum
- I cleaned out my hard drive size down to 22Gb used space leaving 33GB
available
- I have tried all the different options for video quality and checked on
and off the previw window box
- I have tried switching LP/SP
- I hae tried different cable.
- I tried using an external 100GB USB drive
- I tried using a different computer and it does work fine.... Since I also
tried a different computer using the same hard drive i conclude that the
problem is somewhere in the hard driv and the information/configuration
(Memory? WMM? Processing?) countained in it.

Any suggestion will be greatly appreaciated.

Have you inadvertently changed the capture region format -
Is the footage PAL and you have WMM to capture as NTSC
or vice versa?
Are you converting "on the fly"? That is to say that the DV footage
on the tape is DV-AVI, but you have WMM set to capture as WMV?
Have you tried capture with Anti-virus and firewall disabled -
be offline though.
If you are sure that WMM is capturing as DV-AVI and to correct
region, can you make a connection with this problem occuring
and any changes you may have made - software install/uninstall,
Win updates, etc.
 
I tried all that. Finally, yesterday I found the problem. It wasnt the hard
drive, it was the Sprint boradband wirelless PCI antenna. THe first time I
swaped PC's I moved the antenna to the new PC before I turn it on, so I didnt
see the difference. Yesterday after I swaped it to a yet different laptop, it
worked. Since I decided to use now this new laptop, I then inserted the PCMCI
card prepare to start my capturing and ..slow again. thats when I realized
that the only think that had changes was the card. I guess that even being
turned off, it takes processing power or something like that.

Thanks for your tips though.
