A:AnswerI am not sure about portable but it does have a code for a Sylvania DVD player. We have had no issues with ours and we use it for our TV and DVD. Sorry I couldn't help more.
A:AnswerIt should because it comes with a whole book of codes and you pick your TV. We had no issues with ours. The current remote for our TV had been dropped so many times that it just kept giving us issues and this one works great so far.
