 I'm sure this was mentioned already, but using relatively current SVN
 (7308), I am seeing strangeness when watching recordings. The log is from
 a recording that I was watching as it was recording, with no comm-flagging
 occurring at the time, standard TV from a PVR-250. The problem mostly
 appeared when I was catching up to 'real time', but it was anywhere from
 3-10 minutes from that point, so I'm not sure if that is relevant.  Most
 of the log looks similar to this:

 I was watching it at 1.2x for most of the time. I tried switching to 1x,
 but it didn't make a difference, the log still showed tons of the above. I
 will attach a larger portion of the log from the frontend.

 I also still have the weird problem where a forward skip actually skips
 backwards. There are two in the log but I can't pinpoint them. If needed I
 can try to reproduce and log it.

 Let me know if there is any more info needed.
