I'm new to transcoding and don't really understand it that well.
I'm trying to transcode to xvid, but it doesn't appear to be installed on my system yet, I am trying to ASF (or is it AFS?) - anyway. It's painfully slow on my old box (Pentium 450 w/256MB Ram) and is going at 1 FPS.

Is it possible to do the switcheroo to xvid or other format on another, faster machine, and then drag it back to the Myth hard drive?

I think the trouble may be the .nuv format...but then, I don't really understand this transcoding thing that well.

What are you using to transcode? Using nuvexport --transcode will allow you to transcode to xvid. Yes you can transcode on another system and copy it back to your MythTV boxen (Perhaps a search of the forum or wiki if you need details on this...).

I guess I just used the command: nuvexport (without the --transcode)

When using the command you offered, I see this:
Code:
mythtv@pvr:~$ nuvexport --transcode
Loading MythTV recording info.
DBD::mysql::st execute failed: Unknown column 'basename' in 'field list' at /usr/local/share/nuvexport/mythtv/recordings.pm line 65.

Try setting your height and width to 480x480 or smaller (your original recording size)

Nope, changing the height/width gives the same results...
Code:

but, when turning off a bunch (all) of the options, I get success. Now, I'll have to find out which option is causing the trouble.

Here's the one causing the problem:

Code:
Crop broadcast overscan (2% border)? [Yes] Yes


Anytime that's set to "yes" - I get the error.

So, do I somehow remove the -j option? If so, I don't know how. Or would it be some other solution?

Just to add to this. I am havingi the same issue with R30 of Knopix release.

Is this on a bug list somewhere?

PVR250 is the encoder. everything is default (I think, I am too dumb to change anything else).

any why, thank you rkhanso for posting your solution. It is helping me, move Myth out of the closet and might actulay be able to use.

I am amazed on how much of the Knopix version is easy to set up, and then get wacked down on how hard it is to get something like this working.
