playlist, but the :sout option is lost in the process, and you start
watching a video that is never saved.

this to be valid.

If block_Realloc() fails in the function AccessDownload() then resolving
segment->data->i_buffer results in a segmentation error. Instead of continuing
when block_Realloc() has failed, just cleanup and leave the function.
