I posted a note last week about this issue, saying that the problem with my SPs and WLs was fixed by forcing a reindex by either restarting my R10 or forcing a phone call to the DVR service. In addition, I decided to unplug my phone line to see if any of the random phone connections to DirecTV were prompting my problem to come back. Maybe it's too soon to tell, but the problem hasn't come back since I unplugged my phone line (6 days and counting). The problem had come back within a day or 2 previously, so I'm going to keep my fingers crossed that the problem stays away for the time being. Of course if what the DirecTV CSRs are saying is right, I won't get the fix without plugging my phone line back in (Catch-22 anyone?). Whether this is wishful thinking on my part or not, the problem was definitely temporarily fixed for me by forcing a reindex, so I would recommend that anyone try that route first before doing anything drastic like deleting their SPs or wiping out their recorded programs.
