Several players have adjustments for syncing audio/video, e.g, Media
Player Classic.

When sound and vision are out of sync by a small amount, I find it very
difficult to work out which one is leading the other and therefore
whether to make a positive or negative adjustment. If you can apply it
to playing video, it's a lot easier than if you have to stop the video,
adjust it, play it a bit more, stop it, adjust it etc.

True, that would be a nice feature.

VLC allows you to adjust sync pos or neg amount as it plays, Works
easily and well. However that's not a solution for problem but just a
work-around. I can also use VirtualDub and try to sync to audio and
video but the problem is the offset is not constant but changes as the
video plays, e.g. audio becomes increasingly out of sync with video.

All you can do is divide a recording into chunks (maybe at advert breaks)
and set a different delay for each chunk, and then join them back together.
You can at least use VLC as the means of tweaking the delay till it seems
right, and then reading what delay you've found to be necessary, so you can
apply it to the recording using VideoRedo or VirtualDub. A bit of a nuisance
if you have to do it for all/most recordings.

When I used to use WMC for recording, I didn't have a problem with sync,
apart from very occasional recordings. I wonder if sync delay is affected
more by the software you use or by the make/model of DVB/ATSC decoder. If
it's software-dependent, you could try using a package such as NextPVR
instead of WMC for making your recordings. I used to use NextPVR because it
could record more than one overlapping programme per multiplex which WMC
unaccountably can't do - you need two tuners if you want to record two
overlapping programmes.

I now use TVHeadend on a Raspberry Pi (which I also use for logging data
from a weather station) because it uses so much less power than leaving a
Windows PC on 24/7.

I'm checking out Hauppages own WinTv software as I write. I'll check 1/2
hr recording and if it's in sync then good bye WMC for recording
purposes. I'm curious to see file size given WMC creates an 8 Gb file
for an hour recording!!!

I can't be bothered trying to alter sync after the fact. It's only a tv
show for my wife when there's a conflict between two shows at same time
she'd like to watch. Anything more elaborate and it's easier to just
download from a torrent and then you have no ads etc. either.

I'm waiting to receive an external TV Tuner outputs HDMI, Composite and
co-axial. It also takes a USB drive and docs state you can use it as a
PVR. Assuming that does it's job properly and the file format is
something at least semi-common then that's likely a more dependable
means of achieving recording. Maybe I'll let ya's know after it comes
and I try it out.
