Ok so I converted a blu ray mkv to an mp4 for my iphone 4. But i noticed throughout the whole movie there are little audio hick-ups and it sounds like its skipping about a half second of audio causing little hick-ups/pauses. I thought this was just a problem with the quicktime player but i later played it on my iphone and with VLC and got the same problem. These pauses happen randomly throughout the whole 2 hour movie. The original audio track from the mkv is DTS 5.1 surround sound (1500kbps) and i converted it to 192kbps using the core audio format and leaving sample rate at auto. So later i thought i would record all of the times in the video that it hick-uped thinking these were randomly happening from handbrake. One time was between the 6 and 7 second mark. I reconverted the first minute of the video again using the same setting and had the same hick-up at the same time. I did this again changing the output bitrate from 192 to 160 and still the same result. So in other words these hick-ups would happen at the same time no matter how many times i reconverted the video and they DIDN'T happen randomly. Then i decided the play the original MKV file in VLC and at the 6 and 7 second mark there was NO problem, it played perfectly fine. So after all this im assuming it is handbrake messing up the audio since there was no hick-up in the original file.
Heres a list of the advanced setting if it helps at all:
