Formatting the card will delete all the data on it. Buy a new card for use now, then use data recovery software on your computer to try to salvage the contents of the original card.
This camera is ancient by today's standards, at least 8 years old.
Your focus problem is that the back display is very low resolution, so it will never show a sharp image. 9MP should give a decent image when you view it on a computer. If not, you probably need to part with the camera. it is not worth much these days anyway.
Check your camera settings in movie mode for the correct settings for time lapse, normal, slow motion and fast motion. A slow recording memory card will not produce your problem but will take longer to save the file. If you shot the movie in PAL and played it on an NTSC TV, the picture would be in black and white with no sound and vice versa. ALWAYS format the memory card in the camera, never on a PC
Taking it apart and cleaning it is not going to fix this. White rice may remove excess moisture, but does nothing for the salt. You can't clean corrosion that has already begun. As the camera is not currently working, the damage has already been done.
The reason is that the images were not created on the camera in question. Each camera model saves pictures on a card in a proprietary naming protocol, and if your images do not adhere to this, they cannot be recognised by the camera
Two possible solutions.
1. Apple users have reported that the switch on the memory cards performs the file lock function in either extreme positions Lock/Unlock. In some cases they have achieved success in centering the Lock/Unlock switch allowing access to the read/write operation of the memory card
2. Connect to PC
Access drive via windows explorer
Right click on drive (MEMORY CARD)
Select properties
Confirm that RO (Read Only) is not selected.
Selected RO
Try reading card
Repeat properties un-select RO
Try deleting files
If not successful card is likely defective
Hope this helps?
The wrist strap has a thin loop on one end. Thread this thin section (like threading a needle) through the strap hole. (It's on the left side of the camera. There are two openings with a bar over the top of the center of them at the bottom corner of the camera body.) Start threading from the middle of the body of the camera and push the strap towards the bottom of the unit. You may need to twist the loop to narrow it and keep it tight. Once you have this narrow loop through the camera, open up the loop and slide the thick material through the center of this thin loop. Pull the wrist strap until the thin loop tightens around the bar.
This is shown on page 12 of the D30 manual. The manual is available from Canon support on the Powershot page: http://gdlp01.c-wss.com/gds/5/0300013985/02/psd30-cu2-en.pdf. The direct link to the manual is http://gdlp01.c-wss.com/gds/5/0300013985/02/psd30-cu2-en.pdf .
I hope this helps.

(Many lanyard straps for electronic gear work the same way. Threading the narrow section under that bar does require decent near point vision. People who are far-sighted may need to wear bifocals or ask someone younger to assist.)
