Bitrates?

[rtmoore4]

I have been playing with the demo SageRecorder software for a couple of days now, and I really like it. I haven't tried the SageTV demo yet, although that will be next.

I have a couple of little niggles, though, that I would like to point out and see if anyone has any answers/thoughts. I'm going to try and group these into separate threads for forum purposes.

To start with, bitrates... There are a bunch of default settings for capture quality, but I don't see anything that references what bitrates these correspond to or whether or not they are CBR or VBR. They appear to roughly correspond to the default setting in the WinTV2000 application, and I have seen a list of what those settings are. Are these the same?

I see that you can create custom quality settings by editing a text file, but I'm confused about how these options are specified. For example, you can choose a video bitrate and whether or not you want to use VBR, but I don't see any way to specify what the min and max bitrate should be.

Can you provide some suggestions about what bitrate is best for capturing to go straight to DVD with ~2 hours of video? I have tried using the DVD Long Play option, and that seemed to work okay, but confirmation of that, or different suggestions would be welcome.

I have also set the audio bitrate to 224 kHz as I have read that is the max supported by the DVD spec. However, my DVD authoring program (DVD Moviefactory) says that the capture was recorded with 384 kHz audio, once I load it up. Once I set the burn in motion, the program then proceeds to transcode the audio before writing the disc. Is there anyway to force the audio capture to 224kHz, and not have my authoring program have to transcode the audio? (I am trying to lessen the amount of time necessary to go from a capture to a burned disc.)

I didn't check the audio at the time I have look at this later on any way this what I have so far as it stand.
DVD Extra Long Play videobitrate = 2000000 VBR with a PEAK 3000000
DVD Long Play videobitrate = 4000000 VBR with a PEAK 6000000
DVD Standard Play videobitrate = 6000000 VBR with a PEAK 9000000
CVD videobitrate = 2500000 with a PEAK 300000
SVCD Extra Long Play videobitrate = It set wrong
SVCD Long Play videobitrate = It set wrong
SVCD Standard Play videobitrate = 2500000 with a PEAK 300000
He all ready know.

Any way it should set to Hauppauge WinTV which work well.
DVD Extra Long Play videobitrate = 3000000 with a PEAK 4400000 this good for 2hour per DVD disk
DVD Long Play videobitrate = 4800000 with a PEAK 600000 this good for 1 1/2hour per DVD disk
DVD Standard Play videobitrate = 6400000 with a PEAK 800000 this good for 1hour per DVD disk

SVCD Extra Long Play videobitrate = 1152000 with a PEAK 1440000
SVCD Long Play videobitrate = 1600000 with a PEAK 200000
SVCD Standard Play videobitrate = 2000000 with a PEAK 250000

CVD videobitrate = 2500000 with a PEAK 300000
CVD can be more like DVD and at the same time like SVCD spec on the videobitrate can range for low 1152000 to high PEAK 800000.

SHS,

With DVD Long Play, I am able to get almost 2 1/2 hours per DVD. How can this be?

That base line avg at full PEAK.
That depend on the show it self high action show use more highest bitrate do the fast action.
Sometime I could 1hour 45min on one VCD with cartoon
