0Quizdom tablet “video capture” not working

I was asked to invest­ig­ate why some video cap­ture util­ity which is part of the soft­ware pack­age for the Quiz­dom Tab­let was­n’t load­ing cor­rectly on a par­tic­u­lar laptop. Invest­ig­a­tion revealed that quiz­dom used the XviD codec and installs it as part of its setup routine. The laptop in ques­tion already had a video codec installed that was cap­able of decod­ing XviD videos, and this pri­or codec had a high­er mer­it than the XviD nat­ive codec installed by quiz­dom. Dis­abling XviD sup­port in this codec proved to be the solu­tion. Any­one with the stan­dalone MPC-HC codecs or ffd­show installed may come across this problem
