Once FTP-server in TV detects that FTP-buffer is empty, it will close session ..
Solution is to enter setup (in PVRDecoder) and select to "serialize" decoding and transfer.
This will make TV decode video completly before initiating the transfer to PC.
This is obviously slower, and require free space on TV storage media to recieve the decoded image.
But, - this will help owners of slower H-models ..
EDIT: Yey - First on page 100
