One thing i did notice was the shrink factor was 1.6... it seems this is calculated before the ads are cut out, in fact after the ads were removed the files were only 4GB so didnt need shrinking at all. would it not be possible to requatize the files aftes all the ads are removed ??? ie create all the mp2.big files and audio files add up the size of the audio etc and then reqantize.
Thanks all this is one of the best bits of software ive used.
This would be a better way to do it, at present it would be difficult to do correctly as the code is quite messy and disjointed.
I'm thinking of a rewrite of this portion of the code - probably not in BASH script, probably Python or something similar. This wont happen quickly though!

spit2k1,
I have been updateing to SVN Head to catch all the DVB upgrades (not being stuck on an offair channel was way overdue  )
Unfortunately they have changed the way the recordings are named and stored in the datbase. I poked around for a while and eventually came up with some patches that seem to allow the scripts to keep running. I aslo found that I waas having problems on UK DVB where there wre 2 audio tracks, the second audio track was causing mplex to crash. I simply CUT everything past the first audio track, and that sorted out (my) problem. Hope this helps you to update the scripts more elegantly, or anyone who cant wait.

I seem to be having problems with the "using cutlists" bit, in that the cuts dont apear at the right places, I will check if that is a seperate problem.

I seem to have a problem with cutting UK DVB-T the cuting works, but the cutlists from myth applied to project X seem o give an offset of a couple of seconds, odd.

I'm thinking of a rewrite of this portion of the code - probably not in BASH script, probably Python or something similar. This wont happen quickly though!
I have looked at the BASH scripts (never programmed BASH scripts B4) and it looks possibe to do with a few modifications to the scripts.
Maybe
Code: ls -s --size --block-size=M /myth/mythburn/temp
could be used to find the dvd size approx
and replex factor could be generated from that ??
it would mean splitting mpeg2cut-px.sh into two parts but is possible ??
the only other way i could see of doing it (easily) would be to pass the target size of the file to mpeg2cut-px.sh instead of the squash factor
then calculate the squash factor in mpeg2cut-px.sh after the add cut ??
could have a bash (no pun inteddded) myself would probably take me a week to get usesd to the commands though.
I have created an MS Access Program which calculates the approximate size of the cut file by calculating the number of frames to cut by looking at the cutlist. Maybe it may be possible to to create a script in myth to do the same ? So now at least i can work out by hand which combination of files will fit onto a dvd. Will post code if of any interest ?
I think maybe it would be a good idea if there was a webpage or button which applied the cutlist to the origonal .nuv file and reduced the orrigonal file size on the disk think ive seen a cut program on the forum ?

I tried downloading CVS again today, but the diff you listed hasn't been applied yet.
I did use your original script for making a PAL DVD and it seemed to work perfectly (I can't test because I have NTSC). I haven't tested PAL after applying the diff yet.
The trouble I'm having is that it doesn't seem to work either way (with or without the patch) for NTSC. With the original I get a token error, and after patching I get the error I listed in my last post. Sorry to keep bothering you with this. I appreciate the help
Edit: I'm stupid  When I did a copy-paste I added an extra space at the end. It works perfectly now. Thanks spit2k1

Just downloaded and installed from CVS... same error
As I'm a Newbie I have a "silly" question, is their a change in the syntax inorder to get the new version of Mythburn?
I used the following;
apt-get install cvs
cd /myth
rm -dfr /myth/mythburn
cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/mythburn co -P mythburn
cd /myth/mythburn
./install.sh -d

thewights,
I'm not sure why it hasn't hit CVS yet but it's easy to fix this. Just copy the diff that spit2k1 (careful not to add a space after the last \). Paste it into a file called createintro.diff and then patch the original.
Code: cd /myth/mythburn/scripts
nano createintro.diff (paste the text in here)
patch createintro.sh createintro.diff

Is this the command you used?
Code: cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/mythburn co -P mythburn I just tried it and that may fail a few times because of the server load but eventually it succeeds. I got four of these errors bedore I got connected this time: Code: jmd0 mythburn.new # cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/mythburn co -P mythburn
cvs [checkout aborted]: connect to cvs.sourceforge.net(66.35.250.207):2401 failed: Connection refused

Thanks jakep_82,
Couldn't figure out the patch file, so I used vi and edited the necessary lines in the createintro.sh file.
I seem to have a uasable iso file.
Thanks again...
? Does anyone know why nuv2 doesn't work in RA22? (off topic, but I though you guys might know)

I'm guessing you use DVB? If so, nuv2disc would have stopped working because mythtv changed the default recording method from PS to TS. Also, there is no way to select PS recording from mythtv-setup, you need to manually hack the database to do it. The mythtv devs want to remove PS recording all together because they say it is seriously broken. The tools that nuv2disc use do not cope with TS format streams. Fortuitously, the first version of KnoppMyth that shipped with such a mythtv also shipped with mythburn. There are a few things that mythburn doesnt do (as far as I can tell) that nuv2disc did though such as DVDs with no menus.

Greg Frost, thanks for the info
I'm new to Knoppmyth and Linux. I can honestly say that I am impressed with all the work (and help) that everyone has put into these forums. Hopefully, I'll be able to contribute in the future as I become less of a Newbie.
As for nuv2. I have a working version of Mythburn and can now backup my recordings. Life is complete 
Does mythburn record other file formats? (divx, vcd etc)
