MUNICH, Aug 12 (Reuters) - Financial investor General

Atlantic has tendered its 2.4% stake in German media group

ProSiebenSat.1 to Czech investment company PPF, two

people familiar with the matter told Reuters on Tuesday.

By taking PPF's cash offer of 7 euros ($8.17) per share for

ProSieben, General Atlantic is going against the endorsement of

ProSieben's management for a higher rival offer by

MFE-MediaForEurope, which is partly paid in MFE shares,

indicating that MFE faces some difficulties in its bid for

control over ProSieben.

General Atlantic, PPF and ProSieben declined to comment. MFE

did not immediately respond to a request for comment.
