'Kay. Um um among the findings I found that m m most of the curr mm presently available remote controls also include other mm  functionalities um in their design , like operating a V_C_R_ , but they don't seem to be able to deal with D_V_D_ players , but then  there are  surely there are many other functionali functions that could possibly be added to them , but according to the last minute update um actually um we do not want to have all this complicated functions added to our design.
