I have a 4 year old Sony DAV-DZ270 Home theatre which only supports Audio and Photos through its USB Port. It has one HDMI Out port (and No HDMI In) There is no support for playing videos/ movies through its USB. Is there any way to play Movies on a pen drive/ Hard Disk/ Digital Media Player through this player? is there Any way to create an HDMI In port? Are there any cheap add-ons that could help?
