As I've said elsewhere, the AnyDVD log is a super tool but (
) often leaves out diagnostic pointers in this particular area : READ errors.
Most of the time, the AnyDVD log will not show the details of the read error unless these are catastrophic.
For such an error like
TCSectorReader one can almost take this at face value to mean a sector read error has occurred that likely will NOT affect playing the DVD.
When you send in the log you should also make a scan with Nero Speed, a neat little tool that identifies bad sectors.
Download Nero cd-dvd speed.

It's a free program. With Anydvd running in the background, select the tab labeled "scandisc".
Select the appropriate drive letter, and click "start". If Nero cd-dvd speed reports read errors, your disc is (probably) bad and needs to be exchanged--even if it plays fine.
Alternatively, your optical drive could be slowly dying or needs a treatment with a laser cleaner disc.
In any event, READ errors are best diagnosed with as much input about the error as possible.
