[mythtv-users] How do i get the results of commercial break detection?

[VJ]

Hi,
    I have mythTV running without any problem for last one week. I learnt
about the commercial detection and I see some hard disk activity going on
(along with current status shown in 'View Recordings screen that commercial
detection is in progress). But at the end I do not see any effect of all
that. I play the same file and commercials are still there. Can anybody shed
soem light on it?
Thanks in advance.
