HD Link Frame Freezes on Export to Tape
 

Using HD Link 5.2 HDV (m2t) Export to Tape I am getting frame freezes with audio drop outs that last about one second, occurring every couple of minutes.
This happens even exporting m2v files that I had previously successfully uploaded to tape with v. 5.1.
I'm exporting to the same Sony M-15 HDV deck, which seems O.K., I installed a new f/w cable, cleaned the heads, tried different f/w ports, etc.
The m2t files play perfectly on the computer.
Not sure where to look next for a solution.
