Versatility at its best! The AVR 645 not only switches two HDMI; 1.1 sources, it is able to decode Dolby Digital, DTS and PCM audio streams from the HDMI inputs. Add USB audio, iPod connectivity and XM-Ready capability to our EzSet/EQ system and high-current amplifier, and the AVR 645 performs with ease. Equally impressive on the video side is transcoding so that all analog video inputs may be viewed via component outputs, and A/V Sync Delay, which reconnects the timing of sound and images. There is no better combination of sound and image anywhere.

This receiver has a feature called "A/V Sync Delay" that allows you to manually set dissimilar video and audio synchronization that may occur with certain types of Plasma and HDTV's. The instruction for this setting can be found in your owner's manual in the section "Delay Adjustments" or "Delay Settings".Was this helpful? Thank you for your feedback!

Please check the picture settings on your cable box, particularly the aspect ratio settings, which will vary depending on the brand and model of your cable box and on your local cable provider. You may wish to consult with your cable provider for more information on how to adjust the cable box's settings. Some settings, such as a setting to force an analog channel's native 4:3 aspect ratio to 16:9 widescreen to fit your display, may interfere with the cable system's copy-protection feature and cause distortion.Was this helpful?

The remote is only capable of operating one device at a time (unless you have programmed advanced functions such as Volume, Channel or Transport control Punch-Through). When you press the Source Selector to operate your other product, such as the DVD player, the remote cannot control any other product, including the AVR, until you press the AVR Button again. To avoid your problem in the future, always press the AVR Button or appropriate Source Selector before you enter any command.Was this helpful? Thank you for your feedback!
