Okay, here is the situation; I set Lost to record and also set V to record (back to back on ABC). Something happens whereas V does NOT record and Lost gets it's last 5 minutes chopped off. When scrambling to the TV2 to try and record V as not to miss too much I find that mysteriously tuner 2 has NO satellite signal. WTF?? I have signal on tuner 1 as something else is showing. This has happened twice in as many weeks. Is there a know issue with back-to-back timers on the VIP722? How does tuner 2 suddenly drop sat. signal? Totally perplexing and quite frustrating.
