> Has a fix been implemented?
Well, yes, a fix was implemented:
htsback.c:2332
if (back[i].r.statuscode==416) {  // 'Requested Range Not 
Satisfiable'
..
if (back[i].range_req_size == back[i].r.crange) {
..
fprintf(opt->log,"File seems complete (good 416 message), 
breaking connection: %s%s"LF,back[i].url_adr,back
[i].url_fil); test_flush;

If it doesn't work, please activate 'Set options'/'Experts 
only'/'Activate debug mode' and please send me the 
corresponding request in hts-ioinfo.txt, I'll try to figure 
out what's going on

(wow, sure time fly..)
