I have the same hardware now running Fedora Core 5 with the openchrome
I have experienced this problem as well, but only when rapidly moving
backwards and forwards in a recording. I have not tested it but it seems
that ff and rewind are much more fragile in recordings which have NOT
been commflagged and sometimes they do not work on such files.
Generally ff/rwd even up to 20x works fine, but multiple back and forth
attempts will lock up the frontend. I have heard the backend continuing
to record the scheduled program on a couple of ocassions, and I have
just done nothing until that program ended and the recording was fine.,
but it took a 'big-red-switch' recovery.
I suspect that this is actually an X system error, probably somewhere in
the openchrome driver. Since it only rarely allows any recovery I have
not seen error messages very often but I have seen some 'texture' or
'surface' references in error output.
I will have to set up the laptop to ssh in and see if I can induce some
