this has happened a few times and im not sure how to explain it... but whenever im watching programs in the 1hr buffer and FF through commercials, somehow it skips ahead past the last few minutes of the show im watching to the next show. when i RW to the parts that was skipped, that particular part of the show is no longer there, even though i can RW to the parts before the skip. always happens on the ending parts of a show after the last commercial break thats being somehow deleted from the buffers. pressing RW when the new show starts to go back to see the missed part gets me the part prior to the last commercial break without ever showing the skipped endings. what does the H3 do with the last few minutes of buffered shows? any thoughts? bad sectors on a failing hard drive? noticed this happening on tvland, history, science and get tv.
