damn, too much questions!!!
- For EHQ using "string" instead of "uint", does RV8 use the same EHQ setting as RV9? - For RV8, does the first-pass tweak works? Quote:

Yes, the MP4 container is great for HE-AAC and AAC. Like I mentioned, we have MP4 playback working, but it was decided not to make our MP4 renderer available for auto-update, because it would confuse the average user, if he or she then tried to play MP4 video, which we do not currently support, since we have not yet worked out the licensing problem, even though we in fact have our own implementation (not Envivio's). It may be possible to obtain our MP4 renderer through auto-update when trying to play 3GPP content... I am not sure, I get it from our build repository manually.
We could have avoided the confusion with better error messages, as was suggested, but alas, perhaps for Gold. You see, MPEG-4 is all well and nice for interoperability, but when we give away the player for free, the licensing terms are too expensive, I have been told. For Gold, I am not sure if RealPlayer will rip to AAC or MP4 fileformat. I hope MP4.

lets hope that real changes its mind and rips aac directly into .mp4 (not only with gold) and adds a nice error message if someone tries to play a video mp4 (like "realplayer doesnt support mpeg-4 video playback") and than only plays the aac audio...

@datascab: sorry, i temporarily lost your questions:
I did an encode last night using rv9 ehq and cook 5.1. When i play it in the new real player the visual stutters and the sound doesnt play properly. RP 10 has been in testing for many months now, without these problems showing up. Could you please PM me so I can get you in touch with the right person to file a bug report. I can probably not directly help you on this one. You have a 5.1 sound-card, right, which is DirectShow enabled? Question as well, if i want 6ch playback in mpc, where can this be set? This is a question for Gabest in his MPC thread, it works like a charm for me without any special settings. It does appear like your 5.1 setup perhaps is not working right. Make sure your RM playback in MPC is set to DirectShow. Everybody has trouble finding that setting ("hidden" pulldown in Formats menu, end of each line) Is the new aac based 5.1 technically better than the cook 6ch and if I encoded using the new codec would this help with the sound issues above. Our AAC does not encode in 5.1, at least not yet. Only cook does. Which is better is subjective, but in /music/ tests on Hydrogen Audio, VBR HE-AAC scored higher than cook. I used the reg hack for 1st pass vbr ehq and for the 1st time I have found that the resultant avg video bitrate and total file size were out. Predicted avg should of been 1793kps and it ended up 1693kps Predicted final file size should of been 1860Mb and it was 1875Mb This does not make much sense I am afraid. when bitrate appears lower, filesize should be lower. This must be a bitrate calculation problem in whichever encoding GUI you used. But out of 1860 Mb, 15 Mb oversize is not that bad Remember, we have an MSL buffer, and we do not take drastic steps to try to empty it towards the end of the encode, perhaps we should.

What are the codec flavours for the racp.dll? Its own readme file refers to the producer manual and the producer manual doesn't have the required information on setting the bitrate.

HE-AAC codec flavors
Code:
64 Kbps Stereo Music - RealAudio 10 racp 0 44.1 kHz 96 Kbps Stereo Music - RealAudio 10 racp 1 44.1 kHz 128 Kbps Stereo Music - RealAudio 10 racp 2 44.1 kHz https://helix-dna.helixcommunity.org...ug.cgi?id=1108 Co-incidentally, there is also a bug in the decoder DLL that ships with RealPlayer 10 Beta, that prevents playing back HE-AAC in RM. However, both bugs have been fixed, and it will be included in the next Milestone, or perhaps a patch before then.

AAC+ not bellow 64kbps is a shame...

I'd like to see 32 kbps! After all it's made for streaming.

Good points, although cook works very well for streaming. I agree though, and will see if perhaps this can be changed in a future release.

At least Ahead's HE AAC performs better than cook even at 64 kbps: http://audio.ciara.us/test/64test/results.html

Added FAQ in first post. Thanks for all the questions and feedback! Hopefully I included the potentially most frequent ones. If not, let me know.

Damn and blast!
I've just downloaded and started playing with the Basic Preview version of 'Helix Producer 10' and well, damn it, it's just too good! Last night I encoded the Harry Potter trailer that Sagittaire uses for his codec test, and I have to say the resulting encode was most impressive.... damn again! Now, at work, the business uses Helix Producer Plus (v9.0.1). Which I enjoyed using quite a bit coz I like the GUI. But as I'm not into 'borrowing' software from work for use with my home PC's I am stuck with the Basic version for the time being. Very nice work guys, Cheers
