    i want it to be quick, if i want to watch the recording at someone elses house etc, just click burn, take about 15mins to process + burn time (like 3min in my dvd burner), i would consider acceptable. but the mplex could occur at night, after the epg has been updated (which is the part that takes the longest, i think, it was awhile that i played around with this).

    What we probably should do. If you have the code to make it burn the dvd should we put it in a class(es) or dll.

    Have the mplex as another method in there. We can modify xrecord or something that gives it an option to prep the dvd for burning or we can do it in the recording screen, since most shows you do not care about burning. So you indicate on the ones you do for it to run the mplex at night.

    Then you can burn it in about 15 minutes.

    Does mplex cause any problems synch errors etc?? Did you ever ask sub if it might be possible to fix the mpegs so they are not considered "broken". That would save a lot of processing cycles.

    i dont think sub could do anything about it, i could be wrong. but i think i read somewhere that pretty much all capture cards had this problem, frames just are sometimes dropped, the file plays fine, but when you try to use a picky program like dvdauthor, it causes a error.

    ill start investigating this again, do some tests on it.

    over at doom9 mpucoder is writing a *plexing tool called muxman. This might be worth checking out. He is pretty highly respected in this area,

    cheers,
    Colin.

    It looks like a good tool. Too bad it does not have a command line interface as of yet.

    I do like that fact that he takes chapters as frame offsets. So we can pipe comskip data into it.

    DVD Decrypter will also, optionally, produce chapter files as frame offsets. I had tried turning these into comskip files manually and have not been too happy with the results. The frame count doesn't seem to match perfectly and the 0+skip to move forward is a bit akward (and I stil lahven't figured out how to move backwards). plus you have to go through them one a t a time so if you want to skip to chapter 25, for example, you have to press 0+skip 25 times -- yuk.

    i was going to skip the dvddecrypter step by just creating the dvd directories with dvdauthor and burning them with nerocmd. which wud save on space and cut down on time

    I would like to see it as a plugin.

    ok i spent the morning playing around with this more, and to my shock, a defrag harddrive speeds up the process (yeah im an idiot). on my main machine, i hardly ever defrag the harddrive (well once every 2months) and on pvr once a day (only takes around 5mins once a day), so i tried mplex (the longest task before) took under 5mins for an hour show on defragged harddrive, and took about 1 min to put the m2v and mp2 file back together, dvdauthor took about 2mins, now here we can go one of two ways, burn directly with nero (quickest) or create a iso with mkisofs (or something like that) which took about 5mins on defragged machine (about 30mins on undefraged machine, the main thing is the harddrive for this task, using only aroun 5% cpu during all steps). now with mkisofs you can create an iso then burn it with dvd decrypter, meaning every step is free, dont need to buy software, adds about 5mins on, or you can use nero (costs money, but most people have it) and saves 5mins.

    total time for an hour show < 30mins. i can live with that.

    now vote time, nero or mkisofs (free one). im leaning down the free road, dont like having to pay for software if the main software is free (gbpvr), and 5mins, who cares. also we could all save aroun 5-10mins if we process the files after the EPG is updated (im going to do heavy testing on this, since you dont want to overrite the orignal mpeg file with one is stuffed, anyone want to help me test this, let me know).

    i havent looked into chapter points yet, but im sure i can use the comskip files somehow for this.

    so thoughts, feelings, how you doing?

    ok ive got the commands down, theres one that took me ages to get, but here it is (if anyone is interested)
    <table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">mpgtx.exe -d &#91;filename&#93;.mpg
    mplex -f 8 -o newfile.mpg chunk-0.m2v chunk-0.mp2
    dvdauthor -o &#91;DVDDIR&#93; -f newfile.mpg
    dvdauthor -o &#91;DVDDIR&#93; -T
    mkisofs -o imagename.iso &#91;DVDDIR&#93;[/QUOTE]

    the dvdauthor -o [DVDDIR] -T, was the one i was missing, now all of those tools are free and run from the command prompt, im just going to do some speed testing and see how long it takes on various different files, can some other people also test this (just goto www.videohelp.com and search dvdauthorgui to get all those tools (well i think they all come in that package)). once you get the iso you can just burn it with dvddecrypter (also free), or you could leave the last step out and just burn it with nero (since nero has nerocmd).
