Bottom line: Can the output bitrates be editted in disc copier?

I have tried many other free/open source (meGUI, Videora) products to convert various files to MPEG 4 for my iPod, but they all seem to have audio syncing problems for larger files (home movies). They have given options for both resolution AND bitrate for MPEG 4 encoding. I was curious as to what the default bitrate for MPEG 4 is (for both 320x240 on iPod settings and 640x480 on H.264/AVC settings). Also is there anyway to change this from the default?

Thanks in advance for your help

Not sure what the default bitrates are in Disc Copier, but here is what is listed for 'output to file' in Videowave 9. You also can create a custom output. Unfortunately, I only saw the Microsoft MPEG 4 codec listed under AVI, but the user had totaly control over bitrate and resolution.

From what it sounds like, I won't be able to get the level of control I want. My main goal is to have a 640x480 MPEG4 in an iPod compatable format (.mp4 or m4v I believe) that also has decent quality for computer playback. It looks like I can only change the bitrate in VideoWave if I output to AVI or the 3GPP format that you suggested. To my knowledge, neither of these are compatable with the iPod. I don't really want to waste time re-encoding a video in 2 resolutions (1 for PC, 1 for iPod) or even daisy chaining converters (like the iTunes "convert to iPod" option) to get the desired result.

I think I'm going to have to settle for whatever the default is for Disc Copy because I want the 640x480, I would just prefer it in a smaller file size.

I believe the AVC better, good, smaller is MP4 (H.264) format.
AVC better:720X480 audio AAC stereo 48kHz, 32bit
AVC good: 320X240 audio same
AVC smaller: 160x120 audio same

EDITTED for clearity:
These are my goal specs straight from apple.com, if possible I would like to encode at the 640x480 resolution:

Quote

H.264 video, up to 1.5 Mbps, 640 by 480 pixels, 30 frames per sec., Baseline Low-Complexity Profile with AAC-LC audio up to 160 Kbps, 48 kHz, stereo audio in .m4v, .mp4, and .mov file formats;

H.264 video, up to 768 Kbps, 320 by 240 pixels, 30 frames per sec., Baseline Profile up to Level 1.3 with AAC-LC audio up to 160 Kbps, 48 kHz, stereo audio in .m4v, .mp4, and .mov file formats;

MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per sec., Simple Profile with AAC-LC audio up to 160 Kbps, 48 kHz, stereo audio in .m4v, .mp4, and .mov file formats

I found that the Media Manager in Roxio's suite will display the bitrates:

That was the default "H.264/AVC" in Disc Copy. I also tried your video wave suggestion, the "AVC good" quality gives a 1080 kbps rate, and (just for kicks) the PSP 30 FPS, HQ gives a 856 kbps. None of these files were compatable with the iPod. I could also be naive in thinking that bitrates and codecs are the only factors making these files incompatable. The same video rendered with the iPod setting has a 768 kbps bitrate and does work on my iPod (I think this is possibly the middle spec listed above).

At this point I would be happy to simply get 640x480 with a 768 kbps if it worked on my iPod

If this is impossible with the current software, is there any "feature request" forum I could post a suggestion in?
