Is this with a 'real' dxr3 or a Hollywood+ card? My brother is in the
process of setting up a vdr system with a Hollywood+ card and he keeps
on getting similar ring buffer overflows (presumably the output card
starts ignoring the data sent to it, leading to the overflows). My
system has a 'real' dxr3 and I don't see any such overflows: it is
working really well, at the moment.
I _used_ to see a few of them about 6 months back but I can't tell you
whether they disappeared due to a newer version of the em8300 driver or
the dxr3 plugin. I'm currently using vdr-dxr3-0.2.3-cvs from a couple of
weeks back and cvs em8300 drivers from about October last year.
Cheers,
Laz
