You would have to root your tablet to install Google Market. There are some custom ROMs for the CMP738B that are rooted and/or have Market installed already. I don't have any experience using them on the CMP738B (yet), but be sure to read and understand the update process and risks beforehand.
I got MoboPlayer from FreewareLovers and then downloaded the codec from MoboPlayer.com
Yeah that's what I was wondering. I dont want to root it, mainly because I'am not familiar with all that. This is actually my 2nd tablet of this model, the 1st one I had gotten as a christmas gift, and it ended up getting BRICKED Thank you for your help, I've been asking everyone for help and haven't gotten much of a response.
