Might you be running on Mythbuntu 8.10? I had the exact same errors when 
I was running Mythbuntu 8.10 and using NFS for my recordings. I added a 
SBE on the computer that had the NFS mounts and now it records locally. 
I had the same problem with my video files shared out over NFS. I have 
now switched them to CIFS and have not experienced a problem since. CIFS 
might be worth considering.
