Hi,
sorry for my bad english.
I have used a BT878 card for capturing from TV and VHS via
composite with a Linux(now 9.0) and mjpegtools 1.6.2-0.
Now, we have DVB-T and i would like to keep this setup for
some time, it works fine.
Since with DVB-T there are still blocking artifacts, i would ask

Yep - and I think that (more than the speed of the cpu) is what
is causing problems for Dik.

Dik,
Sorry, I made a mistake in the first example (untested code, you
know). I tested this one, it works:
#!/bin/python
import mpeg,sys
in_filenames=sys.argv[1:-1]
out_filename=sys.argv[-1]
in_mpegs=map(mpeg.MpegFile,in_filenames)
reduce(lambda a,b: a+b, in_mpegs).to_file(out_filename)

if 320x480 frame then size_per_hour = 20.0 GB/hr * quality_factor/100
if 640x480 frame then size_per_hour = 40.0 GB/hr * quality_factor/100
DV is a flat ~12GB/hr. Now some have mentioned that as a shortcoming
(you don't get to select the quality) - but it's a feature to me.

Well, I think I was in the wrong branch. I now re-fetched the code without
specifying a branch. It looks like more modern stuff. Anyway, when I try to

Editing is indeed an option: LVE (http://lvempeg.sourceforge.net/).
Maybe someone else will have some suggestions other than install a newer
system ;)
Not me. It is eventually quicker and better to move to a recent distribution.
Just done it for exactly the same reasons Just upgrade, intalls are easy
