I'm afraid the Sony P72 doesn't stand up too well at high ISO settings ISO 100 or 200 aren't bad but once you try ISO 400 you're guaranteed to get that blotchy noise. It's just the camera and you really can't do much about it except increase the light level or scale down the finished shot to make the noise less noticeable.
Experiment with lower ISO settings and slower shutter speeds.

Check your setting. If you are taking real high resolution photos you won't be able to store as much on you memory card. Reducing photo resolution will help.
Boy oh boy there are a lot of tachos here, unfortunatly non i would choose, you need a tacho that picks up the spark pulse from the spark plug, not one that requires a photo tape placed on the machine, Both Husqvarna and Stihl retail good quaility tachos, just place it near the spark plug and it gives a very accurate reading, they are called DET102 the Husqy part no. is 502711401.
You can use just about any photo editing program to reduce the resolution of the photos. For example, in Windows Photo Gallery select "E-mail" from the menu. If you know you're not going to do anything but email the photos, you can reduce the resolution in the camera so as to create smaller photos in the first place using the Still Image Size command in the Shooting menu. However, if you happen to take a great photo you won't be able to make a good print of it because it's too small.
I suggest altering the settings a little and if that doesn't work try using a different software to enlarge images.
Such as windows photo gallery. That's not too good for enlarging just good for keeping the quality up if that isn't good enough try using a free trial of photo shop.

You can set the resolution on the camera for lower resolution. You may not want to do this if you are planning to print the photos on a printer especially if you want larger prints. The best solution is to download the pictures in the cameras resolution and then reduce the resolution using a graphics program such as photoshop to a web format resolution.
There are shareware programs that can also reduce the resolutiion once loaded onto your PC.
You can select whatever resolution you want to print at on your Print(er) Setup.
If your Printer is automatically selecting a 72DPI to print at, you may be trying to print a 10X12 pic size or larger by default due to pic file size created when pic was taken in camera with full 7Meg resolution.
Use photo software to proper size the print before printing. If you want a print larger than 5X7, keep in mind the TZ3 begins to have recognizable noise, reduced resolution due to noise, especially in low light indoor or evening/nite outside shots. You can use photo software to improve and size them before printing. Windows Vista has a built-in photoshop type program. Else, I believe your camera comes with one on disk.
Also, read your manual regarding shooting with this camera.
Resolution refers to the number of pixels or dots per inch (dpi) in an image. Basically, the more dpi that a photo has, the sharper an image is. High resolution is important if you are going to be printing photos (look for a photo-capable printer that has a high resolution, say 4800 x 1200 dpi). If you’ll be e-mailing your images, you may want to save your photos at a lower resolution for faster file downloads.
Digital camera resolution is measured in megapixels (1MP equals one million pixels), so the higher the MP capacity a camera has, the higher quality of images it will produce. Generally you can take good photographs with a 3MP camera.
