I decided I should wait and install the latest 0.9.6 before posting (I was running the beta 0.9.6).

Now that I'm running 0.9.6 and I've spent some time tweaking and improved the detection of dividers (either with SH mode on or using "manual" 45), I am finding I can't duplicate the same level of time drift.

Now I'm seeing a 2 second error in a 1 hour recording. Note that this is not the same HD recording I was testing with previously.

Here is the log from the recording with the 2 second drift. This show is 1:04:55 in length according to the file properties and this is the same duration when I watch it in Media Center

Show Analyzer indicates that the last segment of show stops at 1:04:56.726:
