I am having the same issue as you, all was working fine prior updating to 4.5. However if I enable OMX player it makes no difference, in face it is worst as no videos play.

This issue for me is only related to Mame preview videos. Everything else works fine.

I might try downloading the mame videos again, but does anyone have any idea what the issue could be?

@dpowelly How about some more info about your system - https://retropie.org.uk/forum/topic/3/read-this-first.
