I started with the master system and one outdoor camera due to vandalism and over time I have added more totaling now 4 cameras ( it put a stop to the vandalism!) But seems when I am in live view the program "lags" or skips. I can be watching and then it starts lagging then corrects itself only to lag or skip again. It is usually the sound that does do but the pictures follows as well. Is it my pc that is having issues rather than the Logitech software?

Assuming you are talking about observing via Alert Commander and not via Web, I'd say that at least two things can give those symptions...
1. A WiFi connection to the PC that can't provide enough throughput to keep up with live video and copying clips.
2. A PC that doesn't have the horsepower.
...check your CPUs and Networking in Task Manager to get a feel during those times.
This also assumes you've checked your performance in Diags...HomePlug and Camera...though these would normally affect the weak camera connections, not all...sounds like you are saying all cameras show that issue.

Correct in that when I am viewing live from Alert Commander and not the web. What I did so far was I did a reset on my router ( I know prob doesn't have anything to do with lagging or skipping) but tried it any way as in the meantime I lost two of my cameras all together and the camera in question that was lagging ( which was one) seems to be working better after router reset. I never reset that cam itself. Not sure about my wifii connection but my download speed 7109 kpbs and upload speed is 828( I bet that has nothing to do with it) My laptop is about a year old and is 4gb ram. Windows home 7. It has been working for almost a year with all the cams but guess anything can happen.
In the meantime the two cams that went out I manually reset them both and through working with them can only get one back up and running. This is where it gets strange and may be an electrical issue. When I plug either cam into the top plug by itself ( these are alert cams 750e outside cams) it will work but when they are both plugged in both top and bottom neither work. We replaced the plug itself and still same issue. Must be the outlet is all I can guess. I can believe that the two are interferrig with each other through the router are they? They have been working for months just fine.

OK, since issues are with separate cameras, it is just HomePlug communication issues. Again, run the Powerline and Camera tests under Diagnostics...it should tell you which ones are weak without having to observe it in video. Try an extension cord to other outlets to see which ones are poor/good...not a lot else you can do...it is more the AC circuit/wiring, so the receptacle itself isn't really to blame. If you have a weak one, then putting two cameras on it may be more than it can handle from a data flow perspective. It can be that the circuit is on the opposite side of the house feed ( adding distance HomePlug has to traverse ), or it could also be AC noise from other devices running ( motors, etc ).
Going PoE instead of HomePlug eliminates those HomePlug layers/issues, but requires running ethernet cable from cameras to PoE switch...so not everyone can do that, but if you can...<g>
