Hi, You need to use yuvscalwer. Select the non-black section with the -I USE_ option and select -O DVD -n n. You will then need to tell mpeg2enc to mark the MPEG stream for 16:9 playback with -a 3. N.b. expect to use a lot more bits to encode the scaled-up image. You're probably better

Hi Michael, That doesn't mean everything is necessarily all right now. While I don't see the results on CD yet, I now tried with mpeg2enc -z b and -z t and both results seem to be identical (again...). But it doesn't look good, the edges of the flat areas (anime) is strangely distorted. I

The PVR s/w runs on PCs only but it records to a format which seems to be referred to as PVA. A free PC tool called PVAStrumento lets you demux this, and it stores the results on my Mac's hard drive. It also fixes any errors which occurred while the transport stream was being received. I

HI Robert, Now that I can actually see my video, I have a new problem -- although most of it looks wonderful, parts of it don't look all that good! There's quite a bit of fuzziness at the boundaries between black areas and light areas (i.e. I've seen it with white and pink). Depending

The usual reason for segfaulting mpeg2enc in 1.6.0 and 1.6.1 is a broken version (there are several) of the nasm assmebler. RedHat based systems are particularly prone to this problem. The other alternative is compiling for PentiumPro/P-IV/Athlon CPUs but trying to run the binary on Pentium,

Hi all, I don't want to depress you but it is quite possible that the board's PCI setup is plain incompatible with the Zoran hardware. In my experience with dual 440BXers the earlier ones didn't work so great but the later ones were much better. It could be your very early board just can't

Hmmm sounds like a limitation of the current dvdauthor. The .VOB's on a DVD can be a single MPEG stream split across multiple files to avoid (you guessed it) a 1GB file size limit. I haven't had enough time to play with DVDauthor to check whether it handles this situation. I suspect the

Dear Laurent, The problem you have could be related to an MPEG parsing error in mplex if you are using the stable 1.6.1 or 1.6.0 mplex. This has been fixed a while now in the CVS development version. Otherwise I'm just not sure what the issue could be Andrew
