Are you allowing the tracker time to catch up with your hash rate? I can take 10 minutes to read the same has rate as you are getting on your miner.
This is true, it does take some time to get
roughly the same figures.
See if your shares are getting accepted at your pool the same rate they are reported in your miner.
Also, there is a guiminer-scrypt miner availabe now that makes mining quite convenient.

Are you running the scryptminer standalone to mine on your CPU while cgminer is running on your GPU?
