Tvheadend

I had tv_grab_file working on DSM6.0 for many months, through TVH 4.1.2509. After installing .2436 and upgrading to DSM6.1, I found I could no longer login. Ultimately I removed TVH and reinstalled, as had others on the forums with similar issues. The login problem seems to be resolved, but in trying to reconfigure, I find the XMLTV grabber is missing, along with any/all internal grabbers.

Note that this is a custom grabber and no other part of XMLTV is installed. However it was working fine previously. I have added a custom tv_find_grabbers script, but to no avail. The scripts are in the TVH home directory, with mode 777 and symlinked in /usr/local/bin (and /usr/bin).
