When you click My TV in Windows XP Media Center Edition, you may find that there is a long pause before LIVE TV begins.
Microsoft Windows Media Player may also be slow to respond.
In some cases, you may also notice that %systemroot%\System32\CatRoot2\Edb.log may increase to up to 20 megabytes (MB). Typically, this file is only 5,120 kilobytes (KB).
This problem may occur if the catalog database (Edb.log) file is damaged. The catalog database is referenced by LIVE TV and Windows Media Player. If the catalog database is damaged, there may be delays, and you may experience the problem that is described in the "Symptoms" section of this article.
