VideoReDo does not re-encode, except around the cut points (as does TyTool) with the difference that it works a lot better! I had pixelation using GOP Editor in FAE mode and gave-up on it in favor of VRD+, which has also a wildly better UI.
Further, I've never had a problem with TyTool's multiplex mode--it always works perfectly. I think it may be "other than SD SA Tivos" that Multiplex mode has a problem with. So I find it very convenient to extract-and-mux-and-audio-convert all-at-once, since the ethernet extraction is time-consuming to begin with. My DVD process:
1. TyTool to grab-and-mux-and-convert-audio to PC in one easy step.
2. Import and edit mpg using VRD+. Output as Elementary Streams, correcting GOP lengths.
3. Import to MuxMan which outputs a VIDEO_TS. Burn.
If I'm not making a DVD, this is as easy as "Edit with VRD+ and save". This I do when I just want to play the mpg on my networked Media Players.
Wildly easier than what you and Jetstream are doing!

Got kinda a strange problem, hope somebody can help. I have successfully used TyTool10r4 for 5-6 projects. Learning as I go. But now, when I try to start the GOPeditor from within TyTool I get a message that sez it is editing the file and then immediately it sez it is done editing. It doesn't even start the GOPeditor. If I start the GOPeditor "manually" it seems to work fine, but it won't start from within TyTool. Seems like TyTool is set to some weird Test mode, so it doesn't even open the GOPeditor. Is it something I have set up wrong in my preferences? I have already tossed the whole TyTool folder, and re-downloaded another copy, and another copy of cygwin, but no joy. Anybody got any ideas? Also when trying to create the IFO files I get an error message from bmp2y4m.exe saying it can't find the file to check the location of the source and executable paths. They are just the same as they have always been. If I run bmp2y4m.exe from the command line with the full paths of the source and executable it gives me the same error messages. I've got something fouled up, just don't know what.

Did you change q1 to q2 for FAE? I could tell no difference in the quality using either. The only place I think VRD is better is menu creation.I had pixelation using GOP Editor in FAE mode and gave-up on it in favor of VRD+, which has also a wildly better UI.
Maybe I have a very fundamental misunderstanding of MPEG. But I don't see how you can change GOP lengths without re-encoding. If you have an I frame (signifying the start of a GOP) followed by, say, 40 P and B frames...and then you tell VRD+ to change the GOP length to 30, then after the existing I frame and 29 P and B frames you need a new I frame, right? Plus any B frames with a forward reference could be b0rked.
I don't see how you avoid re-encoding whenever this happens.
Do you have an Intel CPU? Did you set the Quality setting in TyTool.ini to 2? If you don't you get a mess at cut points sometimes. Overall edits look gorgeous when I do them in TyTool.I had pixelation using GOP Editor in FAE mode and gave-up on it in favor of VRD+, which has also a wildly better UI.

So the quality remains the same. Since there are now additional I-frames the size of the file increases by 5 to 15% depending upon how many I-frames are added. I find one problem with redoing the GOP is that on some players the mpeg will freeze or repeat a frame at every new GOP. I try to avoid doing this if I can.
Yes TyTool does a wonderful job of editing, the FAEs are clean and the audio never slips. Sometimes I even use TyTool for "regular" mpegs, though Womble is used more for that, as it is for recalcitrant TyStreams which do go wrong in TyTool.
AMD chip, Quality=1 (the default)
Intel Pentium Chip, quality=2
Intel Conroe C2D, hmm, I wonder if it's better with the AMD setting? I'll have to check that.
Hey guys, I've been getting .ty file extraction speeds of 2 to 2.7mbs. Some have reported much slower speeds and I wanted to see how this compares with your results.
