[mythtv-users] Mytharchive truncating files: "Maximum buffer size exceeded."

[Johannes Rohr]

Dear all,

I am using Mythtv 0.26 on Debian Wheezy. Until a few days ago, 
everything worked just fine, however, now when I try to archive 
recordings to an external USB drive, I invariable get the message


"Failed while running mythutil --copyfile --infile [filename] --outfile 
[filename] Result 132"

When I run the command manually, at some point I see the message 
"Maximum buffer size exceeded file will be truncated, no further writing 
will be done."

and the resulting file is truncated

Does anyone have an idea what is going on and what to do about it?

Thanks,

Johannes
