5 tuner DVR

What's an "OTR Module"?

The HR34 has five satellite tuners and requires a Single Wire Multiswitch dish setup with sufficient free SWM channels for all five tuners.  For many existing customers this may require an upgrade to a SWM16 distribution setup.  

Thanks

Still not sure what you meant by "OTR Module"?

Over the Air Module

OTR is a over the air module to record local TV channels.

Not sure how "OTR" yields "over the air", but the HR34 can use the AM21 Off-Air Tuner Accessory ($50) to record local digital TV channels using an over-the-air antenna. The AM21 has two internal ATSC Digital TV tuners. It connects to the HR34's rear USB port and integrates your local off-air stations into the HR34's Guide Data.

OTA = over the air

Whether an AM21 is required depends on where you're located and whether you need the sub channels that many local stations broadcast.  If you go to www.directv.com/locals and put in your ZIP, it will tell you what locals you'll receive.
