Hi all - post#1, hope this helps someone out;
twice in row I've encoded movies from bluray rips and ended up with discs (verbatim DVD+R SL and DL) that can't be read on either of two Sony players (DVP-585P, DVP-78H) or an old, cheap, toy-like player of a friend's (can't remember the make). I burned multiple copies (three each, to be precise) on two different writers (LG and Liteon) but no go (they play fine on my PC).
I eventually realised what the two source videos had in common - nearly three seconds of black screen at the start, which Hcenc, with its lack of a minimum bitrate parameter, presumably encodes at a few kbs and with which DVD players go into buffer under-run [ETA - or is it under-flow?].
I've read a fair few discussions and queries about Hcenc's peculiar (AFAIK unique, actually) lack of a minimum bitrate setting, generally about blocking on long fades to/from black (which I've not encountered) - I wonder how many others have ended up with multiple dual-layer DVDR coasters at nearly £$€1 a pop (when bought in 10-spindles as I do).

Post the avstodvd log. Make sure to burn the disk at half the rated max speed
On the AVStoDVD edit title/Avisynth tab you can deselect auto avisynth script, and choose trim.
You can get the encode to start 3 seconds into the movie. Here I started at frame 75 and entered 0
at "enter trim end" to get to the end

I just obtained another 'vintage' Sony, a NVP-708H (model after the 78H previously mentioned), and it has no problem with the discs - I guess the buffer-underrun is an issue with some players as much as with the discs.
