Like its peer, the RCR4258, the RCA RCR4373 not only features DVD & DVR functionality for satellite or cable (skip back, skip forward, slow play), but it also includes direct access to new HD over the air digital sub channels. In addition, the RCR4373 also includes dedicated volume and channel keys for ease of use, not to mention individual directional keys. Featured buttons include Go Back (previous channel), Mute, and Guide (useful for digital cable). Most notable about the RCR4373 is its simple device setup with automatic brand, manual, and direct code search methods. The RCA RCR4373 retails for $32.99 and comes with a 90 day limited warranty.
