DVD stuck in my Panisonic VCR/DVD Combo

Question

I haven't used the DVD in this machine for awhile but it is still a fairly new machine and shouldn't be giving me trouble.  I put the DVD in to watch the movie and it wouldn't play, it shows that it is stuck in the tray - it makes noise when I push the open/close button but it won't come out.  I have looked for a paper clip size hole to push to release as I saw on other posts but this machine does not appear to have one.  Any suggestions?
