I need help from some of you experts.
This is the scenario:
I have a DVD with a motion menu. It has several buttons, one of them says "Trailer".
I want to replace it with "Intro".
The default text is dark red, when selected it turns to bright red.
The hard part is:
when you enter the menu, the button labels are displayed with a "typing" effect (letters appear one by one) and the same thing happens when you exit the menu, but contrariwise (letters disappear one by one).
The buttons are in an area of the frame with no motion.
As far as I know this could be a very hard thing to do, but maybe someone can help.

You will have to rip the video form the menu, manipulate the video to replace the current text with something new, then re-encode and put the video back. Depending on the video in question you might be able to do it in an editor, or you may have to use a compositor or recent (CS3 or later) version of Photoshop Extended Edition to clone over the current text before laying down new text.
Easy to say, not so easy to do
The "typing effect" can be done in a number of ways, and it's probably easiest in a real editor (a NLE like vegas, or premiere, or even compositing software like after effects)
You have to be more specific ; ie. do the letters abruptly appear/disappear or do they fade in/out? and do they appear in same spot? or do the letters "fly" off or animate off?
Depending on what exactly you are going for, it might be possible to do in free software too like avisynth
There is no fading, the letters just appear, in the same spot, no "flying".
The only animation is:
when you enter the menu, letters appear starting from the first one of the first button to the last one of the last button,
when you exit the menu, letters disappear starting from the last one of the last button to the first one of the first button.
Again, any editor with text overlay can do it. It could be done with avisynth and subtitles, or even Windows Movie Maker and it's text overlay. All you are doing is adding a new text overlay at regular intervals (one for each letter) until all the letters are in place. Taking the letters away is as simple as running the original clip backwards.
I'll see if I can figure it out.
I made it with Premiere.
Not easy and time consuming, but above all, useless.
No matter how I set the parameters, the exported video has a visible loss of quality, especially on the text "labels" of the buttons.
was the original interlaced?
what were your export settings? (bitrate etc...)
were the text labels already low quality in the preview before exporting?
The original seems to be progressive.
I tried to export as an MPEG-DVD (quality set to max) there is a quality loss, I tried Uncompressed Avi also, still quality loss but lower.
Yes, the text was already low-quality in the Premiere preview monitor.
Do you have preview in Premiere set to full , or reduced resolution/quality?
Is this 23.976fps footage with telecine removed? if you didn't remove pulldown, PP might be trying to deinterlace and you would get bad quality. This would be especially noticable around titles/letter edges.

Ok, this is what I did.
I used what I call the "fake avi" method wich I learnt from this guide
First thing I extracted the cell I wanted to edit with VobBlanker.
Gave the .VOB to DGIndex. This is the preview Information panel:
Saved the .d2v file ("Demux All (Audio) Tracks" and "Honor Pulldown Flags" both selected).
Then I loaded the .d2v file into VFAPI Reader Codec and ended up with an .avi file wich I call fake because it needs the original .VOB to work.
I loaded this .avi into Premiere, made all the text editing, exported it, bad quality on the text.
I don't know if this matters but the text is red, I noticed red text is hard to render on the edges.
Premiere was set to automatic quality, I just tried again with high quality selected, same thing (we are talking about the preview quality, right?)
If you're in PAL land and this is a PAL disc, there should be no telecine flags to remove
red does show up worse than other colors when 4:2:0 YV12 is converted to RGB for display. The color information is a lot less in YV12 formats. However, it would already be bad in the original DVD (which was 4:2:0 YV12 to begin with). Processing it with Premiere should only make it slightly worse for the reasons mentioned earlier
The preview quality only affects the preview, not the final render
Posting an actual sample might help narrow down the problem

I am in Italy (so PAL land) and this is a PAL DVD.
I know the preview quality affects only the preview but since I had already said that I set quality to max for the output files I assumed we were talking about that.
What do you need exactly as a sample?
I am on a slow-speed connection so I don't know if I can upload what you are asking for.
what I would like to compare is the original , vs. what you did in premiere to see if the discrepancy can all be accounted for by mpeg2 compression or is it something else?
you could use dgindex and mark in/out to cut a .m2v (video only) sample, enough to illustrate what's going on. It should only be a few MB, and you can upload it directly here if <30MB. Alternatively you could use a free host like mediafire.com
what doesn't make sense to me, is that your uncompressed avi is showing the same "bad" quality (slightly better than using mpeg2 for export). It should be "near" perfect, with the only losses from colorspace conversion. This suggests to me either you are doing something wrong (maybe wrong sequence settings?) , or some incorrect settings were used
Also, what version of premiere are you using?
I really want to thank poisondeathray for his help on this.
Thank you very much for time and kindness!
just for completeness and to fill in the gaps for people who might stumble on this thread, we had some pm's back and forth and got it sorted out.
to summarize, most of the problems were solved by getting the right settings for sequence and export in premiere
if anyone else has problems, just make a new post, or continue in this thread
