How can i connect my EP30 hddvd player to my HT-THX25R home cinema system?
Use an HDMI cable to/from the HT-THX25R, or HDMI from the player to your HDTV for video and an optical or digital coax cable for audio from the Player to the HT-THX25R.
EDIT EDIT
Sorry, you only have an analog stereo input so you can't get surround audio (except matrix with Prologic) but you can connect.
