biker19 . . . I'm OTA only, using an indoor antenna, and only about 5 miles from antenna towers. I have multipath problems due to a lot of trees surrounding my home. Multipath is worse if it's rainy/windy. So far I'm very pleased with the Philip's performance. Reception is better than the ATSC version of the Lg, Samsung and Panasonic recorders. Also, see my comment to "amesdp" below.
amesdp . . . I agree 100% with wabjxo on the signal loss issue. As noted above, I experience multipath in my area resulting in a temporary signal loss (the signal loss is often only for a few seconds). The ATSC version of the Panasonic I tested (and returned) would stop the recording when the signal loss occurred. Due to this recording off / recording on process, the "gap" in the recording was of much longer duration than the actual signal loss. I much prefer the Philips approach of recording right through the signal loss since it results in a shorter duration loss in the program I'm attempting to record.
Chuck44 . . . Multipath issues can cause a temporary complete loss of signal. What happens is that the ATSC tuner receives not only the main signal from the broadcast antenna, but also additional echos of the main signal that are reflected from other objects (trees, buildings, etc.). The tuner cannot "decide" which of the various signals it's receiving is the correct one and basically cuts off all signals and "re-boots" itself. This may not be the most technical description of what occurs, but is how I can best understand the phenomena. By the way, multipath is NOT due to a weak signal. I get a very strong signal, but still experience multipath.
