Channel frequencies lost when guide listings updated

[Ari]

I've found that MCE2005 is now deleting this key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\TV System Services\TVAutoTune\TS64-0'
.. each time I download the latest guide listings.
Has anyone had this issue before? Any ideas on what the cause is?
I have been using MCE for a couple of years, but never seen this until this week...

After spending hours investigating, I tracked it down to the code that was causing it, but didn't know how to prevent it happening.
I used the MCE reset tool and that did the trick.
