I have had several programs not recording on occasion. Two in particular are BBC America and Steven Colbert. It is kinda hit or miss - sometimes they record and other times they will not. Is it perhaps guide related? I have included a portion of the log. The Steven Colbert show last night was a new episode and scheduled to start at 11:35.
