My workflow is reasonably simple
1. Rip the HD-DVD using dumphd which calls aacskeys to decrypt the keys. Since there are no new AACS keys for HD-DVD you don't need to use anydvd
2. Run tonmt (which is a shell for eac3to and tsmuxer) to extract the video and audio track of choice. I always grab the TrueHD track if it's there or else the DD+ one
3. Now have got a large file called .ts
4. Run x264 to encode to a smaller size. I use this command line rather than a GUI since it's the same every time apart from the movie name
start /belownormal /b /w x264.exe --profile main --level 4.1 --preset fast --crf 21 --thread-input --keyint 24 --min-keyint 2 --ref 3 --ipratio 1.1 --pbratio 1.1 --rc-lookahead 40 --me dia --subme 2 --partitions p8x8,b8x8,i4x4,p4x4 --trellis 0 --weightp 0 --output %1.264 %2.avs
where %1 is the prefix of the output file and %2 the prefix of the avisynth script. This was suggested to me on the doom9 forum and produces good results. Note you don't need --weightp 0 if your target player is not an Oppo BDP-80 since that player currently does not handle weighted p frames (the 83 does as does the PS3).
To save time and since I don't mind about how much space the output file takes so long as it will in a DVD9 I use one pass constant quality 21. This produces a video file from 3-6GB in size depending on the movie length and profile of the video.
5. Then mux that output file .264 with the best audio that is available - either TrueHD or DD+ using tsmuxer and choose the AVCHD output format
6. Burn the contents of the AVCHD folder (usually a BDMV and CERTIFICATE) folder) to a DVD using Nero (Imgburn will work also apparently) making sure it's burnt as UDF 2.5
