Ling-Ling not one battle monster kind of battle monster.

Here is a very specific command that I'll post publicly, as someday one other person just may search for it:

The following loads in a MythTV NUV file containing a letterboxed, telecined film (...or Battlestar Galactica episodes). The video was captured at 528x480, 29.970fps. It crops the borders, detelecines to 23.976fps, and scales in the X-dimension to 480x360. This 4:3 aspect ratio makes it possible to play fullscreened on my Philips DVP642/17, which will get stretched back to the original 16:9 by the widescreen TV. The codec is lavc's msmpeg2, which seems to be the only one that works with the Philips player. Since the NUV is from digital cable, I just pass the AC3 audio through. You could also mp3lame it.

mencoder -vf crop=528:360:0:60,pullup,softskip,scale=480:360 -ovc lavc -lavcopts vcodec=msmpeg4:vbitrate=1200 -oac copy -ofps 24000/1001 input.nuv -o output.avi

Add two-pass options if you like.

*whew* trial and error on mysterious hardware sure is fun. If only there was some kind of universal computing machine I could use to output video directly to the big TV.

Other than the potential issues with your Philips player, I strongly reccommend avidemux for working with MythTV recordings, it works great.

I wish I knew more about the status of unencrypted digital cable broadcasts up in Ithaca, NY where I'm moving, I'm thinking of getting a Linux-compatible HD tuner board to replace my paperweight MyHD MDP-100 (no Linux support whatsoever), but I KNOW there won't be any OTA reception so the card will be kind of useless if Time Warner encrypts all of their digital signals.

I actually use avidemux to chop the commercials out of the completed stream, since it only reencodes around the cuts. But I still don't have a lot of trust for the program because I could never get version 1 to do any work. Transcode is still my weapon of choice, but MEncoder is the only program I've seen that actually has a decent inverse telecine filter: pullup. Because I know that BSG was shot in 24p, it's the only quality savings I can get from my already-digitized-and-noise-filtered-by-Comcast 360 paltry lines of video.

Uh sorry.. more bitter than I thought.

Anyway, maybe someone on AVS Forum would know the status of your cable. I got lucky, as Comcast leaves unencrypted the broadcast channels in HDTV and most of their digital cable.

Also, this whole NUV thing will be a moot point soon. I'm (stupidly) using the current CVS of MythTV, and all my digital recordings are now saved as good old fashioned MPEG-2 program streams.
