mamos22,
I was joking about the firewall.
I had various problems with either missing or broken up sound on my first 4 or 5 goes, but eventually stumbled on a combination that worked for me.
By trial and error I ended up with a three step process:-
1) Use the DVD Decrypter to create the vob file from the DVD as per the link above.
2) Use Xmedia Recoder software (selecting the preset 'Humax' profile) to create a ts file. There's only a profile for the iCord, but it seemed to work.
3) Use AV2HDR with FTP to remux the resultant file onto the HDR.
If I missed step 2 or used different preset for the Xmedia, then the final sound was bad or missing. Not sure if I could miss out step 1, but once I'd done that I kept using the same source as I knew it had the sound on it, just tried variation of step 2.
You'll gather, this is not in my area of competence, but I got something that worked for me and also ended up with a version of the film that plays on my Walkman.
