UHF remote control. However, an 8PSK module can be installed in place of the UHF remote and allows the receiver to decode the format used on most Dish Network high definition programming. These units are superior to DVD recorders for time-shifting HDTV programming, as most DVD units down-convert OTA HDTV signals to standard-definition to match the limitations of the DVD standard. An HDTV FTA receiver with ATSC capability and USB storage can record one channel from a terrestrial or satellite DTV transport stream entirely losslessly, although the on-screen guide for terrestrial reception is often limited and viewing or storage of analog NTSC channels is not supported. Controversy Availability of free programming While significant amounts of programming remain free, there is no assurance to viewers that any individual broadcast currently available free-to-air will remain so. Some will inevitably move to incompatible signal formats (such as MPEG 4:2:2, 8PSK, DVB-S2, or MPEG-4), change from free to encrypted, move to different satellite locations (often across bands, where C band reception requires much larger antennae) or shut down entirely. Many of the signals are backhaul or "wildfeed" video destined to individual stations, or are feeds to terrestrial transmitters programmed remotely. These were not intentionally created as direct satellite broadcasts to home viewers, but often had been left unencrypted (in the clear) on the assumption that few people were watching. As free-to-air receivers became inexpensive and widely deployed in the 2000s, many of these feeds moved to C band (requiring a huge dish), were encrypted or changed to incompatible modulation or encoding standards which required more advanced receivers, even though the corresponding terrestrial television broadcast may still be free-to-air in its home community. The onus is on receiver vendors to voluntarily indicate, whenever they use lists of currently available FTA programming for marketing purposes, that free channels frequently may appear, move and disappear, often on a permanent basis, with no advance notice. One North American example was Equity Broadcasting, once a major source of small local terrestrial stations on free satellite television. Equity filed for Chapter 11 bankruptcy on 9 December 2008, and most of Equity's terrestrial stations were sold at auction in mid-2009. As many of the stations (such as New York state's WNGS and WNYI) were sold to Daystar and now originate nothing, the corresponding unique free-to-air signals (Galaxy 18, 123°W) are no more. Even where a signal still exists, an incompatible signal
