Are there 2 or more heat settings? If so, use the lower one.
Also, it may be that you need to use more liquid. I say this because you say the meat is dry. Crock pot cooking requires plenty of liquid.
One of the advantages of a crock pot is that it does long time cooking which tenderizes tough cuts of meat. Perhaps you're using tender cuts which do not do well with long time cooking.
When you look at the food during cooking, the liquid should just barely be moving. If it's boiling the temperature is too hot and it's time to get a new pot. It could be that the thermostat is not working.
It's normal for the food that splashes up on the sides to brown and charred. Again, it sounds like the recipe didn't provide for enough liquid. Another idea is that the pot is too big for the recipe. That would cause there to not be enough liquid and for there to be dry sides on which food would char. What size of pot did the recipe call for and what size is your pot?
If your pot is oval you may have difficulty with smaller recipes because it provides too much surface on which the food spreads out. When the food is not concentrated in a small space it will cook faster. The oval pots are made for larger amounts.
