[mythtv-users] Proper PVR 350 settings

[Timon, John]

Jason, I believe what you are describing is interlacing.  The PVR350
captures interlaced.

if you are playing the mpeg stream back on a progressive display, i.e.
computer screen/hdtv monitor you should enable/use deinterlacing.  There is
an option in the mythtv tv playback settings (IIRC) to turn this on.

Using windows media player, I wouldn't even begin to wager a guess as to how
to enable deinterlacing.  Prolly need to transcode with something like
virtuadub or some such tool.

Subject: [mythtv-users] Proper PVR 350 settings



    Hi,

    I'm working on getting my PVR 350 based system setup properly, and I
think I don't have the right settings in my recording profiles to get good
output from the 350.  Currently, I'm able to record video (been going for
about 15 hours now).  As I haven't fully cracked all the problems on my
frontend problems, I've been copying the resulting .nuv files to my windows
system to see what the quality is turning out to be.

    When viewing the files on my windows system (using media slayer), I see
a lot of what looks like interlacing.  In high motion parts of the video, I
get horizontal black lines in the output.  The problem isn't so bad in
normal TV, but the Simpsons looks _horrible_, and I can notice the problem
at other times in other shows.  I tried to take a screen shot of the problem
but media player didn't want to cooperate with that effort.

    My current recording settings specify MPEG2-PS with a bitrate of 4500
and max bitrate of 6000.  Should I be using MPEG2-PS?  MPEG2-TS?  Something
else?  (Is there documentation on what the difference between the video
formats are?  I haven't _any_ clue what the difference between the TS and PS
flavors of MPEG2 are, but I've got that enquiring mind...)

    Is this a problem that I can address?  I'm imagining that viewing files
via the frontend on my TV (using the 350 TV out) will be a bit better, but I
will probably want to view files on other systems, too.  I seem to remember
someone posting about this problem recently, but I couldn't find the
messages in the archive, and I can't quite recall if it was in the dev,
users, or ivtv-devel list, which makes searching harder.

    Thank in advance for any suggestions,
    Jason
