Hello.
When I play Adjustment Bureau from the Blu-ray rip foler using Total media 3 I get smooth playback.
When I create an mkv from the rip and play it in TMT3 I get choppy video.

Why is it so?

Also when I look at the rip and mkv using media info I get differing codecs. I thought it should be the same.
Please explain?

The media info output follows for Blu-ray:

make sure tmt3 is using dxva codec such as ffdshow tryouts.

I'm interested in why the codec would change between playing the rip and playing the mkv.

TMT3 has awful MKV support.

It's the same codec, VC-1 .

So if the codec is the same why would tmt3 play choppy on mkv but smooth on original rip?

This is only the second movie I've tried. The other one worked fine but it was not vc-1.

TMT handles MKV's very poorly. It's not designed for it.

TMT5 has far better MKV support FWIW.

I've got TMT5 and some MKV playback is still atrocious and choppy. It's not down to my CPU or network speed either.

If you want a PC solution for MKV playback, it's hard to beat the following:

MPC-HC
LAV Filters (LAV Audio, LAV Video, LAV Splitter)
madVR

All freeware and/or open source. I use a more advanced player with the LAV Filters and madVR called J River MC16. It has library management capability so that when I rip my BD's to MKV, they are available to any machine on my network. Full bitstreaming and/or decoding (dts-hd ma can be decoded by LAV Audio by using the dtsdecoder.dll from TMT) to PCM. Absolutely awesome.

trial of tmt5 has the same issue for me.

Their MKV support in TMT is definitely a work in progress. I'm sure it'll improve over time.

Are your MKVs on a network drive? If so I struggled for a long time trying to understand why my MKV playback was very bad under Windows 7 on a network drive. If I played the content locally it was fine.

The root cause was a setting in Windows 7 that will throttle network performance when multimedia was being played. Unfortunately also throttling the playback of the MKV itself.

The fix is a simple registry change to turn off the network throttling:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile]
"NetworkThrottlingIndex"=dword:ffffffff

After I made this change I've no longer had issues with MKV playback regardless of the player I used.

Interesting. I hadn't seen that value before. Thanks for posting that!

I did a full write up on the MKV playback forum.
