Post subject:  how do *you* record from satellite and edit and write to dvd
to make things easier for me:

some here will record using Knoppmyth, from satellite to a file on the computer.
will do some editing after that (headers/footers off, advertisements away)
and after that burn the file to a dvd to show it from the standalone dvd recorder on their tv-set.

as i wrote in my previous topic here: i get not-editable *.mpg files.
(am bound to a win98se system -magix video de luxe 2005 available, or a suse9.3 system, where cinelerra does not work on (better said: i cannot get it working due to dependencies which *i* am unable to solve; a rpm-package for suse9.3 is not available).

hope some of you can offer something, or point me to a howto on this.

thx,
rob

- Set up so you can record from your source. With a satellite box his will involve setting up an "external tuner script" to control the box. Search here for the quoted keywords, (check the require all terms box!!!) or alternately for "IRblaster". Also see the User Manual on the MythTV wiki - http://www.mythtv.org/wiki/index.php/User_Manual:Detailed_configuration_Backend

- Review the recordings in the frontend and set the appropriate cut points. See the MythTV wiki for details on editing recordings - http://www.mythtv.org/wiki/index.php/User_Manual:Daily_Use#Editing.2C_Transcoding.2C_Removing_Commercials

- You can do "lossless transcoding" at this point if you want. Search here or on the KnoppMyth wiki for the quoted keywords. This is also covered in the User Manual.

- Use MythArchive to select the recordings and export the files to create a disc. See the MythTV wiki for more details - http://www.mythtv.org/wiki/index.php/User_Manual:Daily_Use#Archiving_Recordings From the main menu it's path is: Optical Discs -> Archive Files

To make things easier for us, please read the rest of the User Manual on the MythTV wiki which answers most of these questions and many, many more.

OBTW - This is how I do this on a regular basis, minus the satellite complications.

You can do some editing on your MythTV box, if you set up a transcode profile as lossless, then mark the sections you want to cut out during playback, then transcode the file using that profile, it should cut out the marked sections.
Though, IIRC your MythTV Box isn't that powerful, so it might not really be practical for you.
I've run into the "Wrong MPEG Soundtrack problem" in which the soundtrack you hear is either silent or audio description and the real soundtrack is on a different channel, so I've had do something else.
I copied the file over to another machine (running Kubuntu 7.04), I then ran ProjectX on the file, then used mplex to re-multiplex the video and the correct audio file, I then loaded it into avidemux and saved it out as a MPEG-TS, then copied it back over to the MythTV box, over the original file.
There was no problems with this as the ads had already been transcoded out, but if you had issues with that, you can copy the file into /myth/video and use the video burning functionality of MythArchive.
I did this with a series of DVB-T files I had previously recorded with an earlier version of KnoppMyth, but at the time I wasn't able to top and tail them before burning, so they had been sitting on my main machine for some time, so after running ProjectX and mplex on them I edited them using avidemux cutting out the top and tail, saving them out as MPEG-TS then copied them across to my KM box /myth/video directory and burned them on to DVDs using MythArchive.
If you need to create a DVD on another machine, there is an application called Kmediafactory, but I don't know if it's available for SUSE9.3. I haven't used it myself, yet, so I don't know how good or easy to use it is. Of course there is K3B for burning your DVDs.

Mplex, avidemux and KmediaFactory are available from the default (K)ubuntu repositories.
ProjectX is a java based app and requires the Genuine Sun Java.

Lossless transcoding is computationally cheap, since it's only doing serious work for a handful of frames around your cut points, and just passing the rest of the frames through untouched. As a result it should work fine even on low spec hardware. On my system it's speed is almost completely determined by the disk read/write time, and it only takes marginally longer than just copying a file.

new problems here!

after using tjc's method of making an iso in MythArchive, i run into the following:

my KM system has a cd-writer mounted (used for installing KM), there is no dvd-writer present at the moment.

in MythArchive i choose:
export video files | create dvd
dvd is preselected and cannot be changed
(single layer dvd)
i choose to create an ISO image
i choose the file to transform to iso
after the script ends (with no errors shown) i have a
*.iso file in myth/tmp/work

i transferred the iso file to my win98se machine (with a dvd-recorder mounted)
i tried to play the iso in VLC (actual version): it plays fine: fluent video and good sound.

with Nero i try to burn the image to a dvd-rw disk (enptied)
Nero refuses and says CD-r or CD-rw needed (!)
i used an emptied CD-rw disk instead
nero writes the iso to the cd-rw without problems.
after that the cd-rw plays nicely in VLC.

i take the cd-rw out to my standalone DVD player (quality Yamaha player, capable to all formats) and telly combination
the video can be played but is 'slowed' with dropouts in video and sound...
unusable...

my question: why does MythArchive pretend to make an dvd-compatible iso and actually makes an iso fot a cd?
is this while the hardware cd-rewriter is mounted in the system and not a dvd-writer?

is there a solution for the bad quality of the video as shown on the standalone?

(hope this does not upset any of you :roll: )

thanks,
rob

DVD .ISO is DVD-Video compatible, I was trying out 5E50 on a slowish box, but was not equipped with a DVD drive, so I had to pull the .ISO from that machine over to my main box.
I think your problem is with Nero. I've been making lots and I mean lots of burns to DVD-RWs to allow someone else watch the programmes I've recorded and obtained by other means *cough*. I've had no problems, other than the occasional sound channel problem and the length of time it takes to transcode from non PAL-DVD resolutions.

How big is the .ISO image anyway?
Have you checked that you have set the DVD output format to PAL?

## which program do you use to burn your iso?
Quote:

## the iso file is about 125 Mb (it is a very short recording i did as a test for the making of an iso and a dvd..)

Quote:

## i have set output to pal a.f.a.i.r.
but will do a test tonight again to be sure.

EDIT:
i just converted my win98se machine to a suse9.3 machine (harddrive is in a 'quick change slide')
i got the same *iso file from my KM box to the Suse machine and burned it with K3b to a DVD-rw disk..
K3b says in the first screen "iso9660 image' (autodetect), with volume id. MythTVBurnDVD.
it **does** write the iso image to the DVD disk.
after that, i cannot play the disk under Suse (multimedia shortcomings ;-) )
but when i take the disk to the standalone player, it plays nice with sound.
**no** dropouts now...

will have a look when i burn the iso to the cd-rw, using K3b, now..
to see how it plays in that case...

EDIT2:
when i burn the iso to a cd-rw using K3b i get the same problem as with Nero,
so it seems a 'dvd-iso' can, but should **not** be burned to a cd...
