.wtv files seem to have fewer motion artifacts than
alternative compressed formats.


I'd have though that all off-air recordings, in DVR-MS, WTV and TS
formats, would be identical apart from the wrapper around the data. So
I'd have expected the same degree of motion and JPEG compression artefacts.


I think the point is that .wtv files aren't compressed. That's why they're
so huge. The off-air data just gets shoved onto the drive.
If you use some other storage format, it takes a lot of horsepower to get
the video onto the hard drive...and back off again.
I can record 4 channels and play a .wtv recording simultaneously with a
2.8GHZ dual core pentium. Virtually all the horsepower is consumed
by rendering the video.

The reduction in artifacts is due to the lack of compression.
I think the limit is the disk drive bandwidth. When the system is
busy, I sometimes see major pixellation on a scene change, but it
recovers quickly and the frame skip is pretty effective.

Only complaint I have is that I messed something up and can't seamlessly
skip forward any more.


Have you tried another player, something other than VLC and WMP? I've
tried VLC a few times over the years and it has always been prone to
crashes, so my preferred player is MPC-HC.

Here's a comparison of VLC versus MPC-HC, one of many:

The latest release of MPC-HC might be the last, but I'll use it until it
no longer works.
