Hi,

My new 500X2 won't rewind .mkv movies!   Sad Is this something wrong with my player or is it a bug in the firmware? Am I doing something wrong?

Fast forward works fine - really cool the way it also speeds up the sound!

Help!

Please read the guidelines for posting media problems. Use mediainfo (on a PC) to extract information from the file. 


We have lots of advice on how to make you own MKV's. If they are torrents. well we have no idea how those where made. PC MKV players are desinged to deal with th badly encoded media found on torrent. VLC prides itslef on doing that. But hardware players have no such flexibility or tolerence.

Sorry I posted in the wrong place! I'm very new at both players and forums - this is the first forum I have ever joined!

I opened the file in MediaInfo and got this:

I made the mkv for the player myself using MakeMKV after ripping the original DVD with RipIt4Me and DVDShrink. The original rip was done some time ago as it was meant to fit onto an ordinary DVD. I changed over to mkv because it is more elegant and generally easier to use on the player. I have lots of these all done in the same way. None of them rewind!

I think that is all that is relevant to my issue. Is there any further info that is needed?

Download MKVtoolnix and use MKVMerge GUI to remux. We don't get a lot of mpeg2 mkv's. Most people are converting to H264. Try remuxing first, transcoding takes far to long amd might not work.

Thanks jer1956 for the quick response!

So what you are saying is that my mpeg 2 videos won't play properly in the 500X2 and that I need to remux them all to H264?

I don't understand how the 500X2 can struggle with formats that have been around for ages?

If you are sure then I will give it a try. I would rather learn this now before I copy everything over and spend ages sorting them and converting straight to mkv.

I just thought that DVD shrink although old was still good? Has always just worked for me.

I don't have any HD stuff yet - is that the reason for h264? I do plan on going HD in the near future, I suppose I just need to take this opportunity to sort out all my old files!

No!
Remuxing using differnt muxing software should be tried first.

Using MKVToolnix, there's a one tool called MKVMergeGUI (GUI for MKVMerge),
http://www.bunkus.org/videotools/mkvtoolnix/

put your MKV into input file menu, click start muxing, it quite fast - it will remux your video and audio into an MKV file again. try to play this file and post the result here.

You don't sleep! Thanks for the reply.

I did as you said, but it didn't work. The file still won't play in reverse!  Cry

What does remuxing like that do to the file? I also ran the resultant file through MediaInfo and got this:

I'm no expert, but it looks much the same to me.

When I try to rewind, the movie just freezes until I press play again. Same as the original mkv.

What do I try now?

Try with a short name and short path
Your file is located :
J:\My Videos\Mede8er\Movies\Animation\_Kyle\Ice Age\03 Ice Age 3 Dawn of the Dinosaurs (2009)\Ice Age 3 Dawn of the Dinosaurs (2009) (1).mkv
Try to rename it and move it like :
J:\movietest.mkv
and tell us what this will do.

A odd thing :
Code:
Scan type : Progressive
Scan order : Top Field First
If the video is progressive, then it doesn't have a top and bottom field.
If it have a top and bottom field, it is not progressive but interlaced.
I believe mkvmerge doesn't recognize the video correctly and therefore it write false information about the viideo making it difficult to read by the player.

Hi jaunedoeuf,

Thanks for the idea - I tried moving the file to the root of the drive - no change!

The scan type and order you mention is meaningless to me! Sorry. Any ideas how I can fix it?

This is not the only file I have that does this.

Major bummer!  Sad So you reckon the field problem is the issue?

If you guys say that's what I gotta do, then I gotta do it! Better now than later.

1. What software should I use and what codec? These are all SD movies. I think it affects most of my movies!!!  Angry

2. What have I been doing wrong? I need to work out what is causing the problem so I don't keep doing it. Is it because I have been using such old software? If so, I can't understand why as RipIt4ME, DVDShrink and DVD Decrypter seem to be well respected all over the place.

3. What do you recommend I use in future to rip with so as to avoid this problem?

4. The Mede8er seems to be the only thing that struggles with my files. All the software players have no problems at all. Why is Mede8er so picky!? I thought it was specifically designed to play almost anything you throw at it - now I find out that it doesn't like old wavs, old wmvs, avis from video cameras, some mpg files, and now this issue! What next "aaarghhh!" (frustrated!). I am starting to feel like I need to re-encode everything specially for the Mede8er, just to be safe.  Shocked

Thank you so much for your time and trouble in helping me out. I am very grateful! You guys rock!  Grin

Using handbrake 0.94 (not v0.95 - it has indexing problem) - you may choose normal profile, and MKV container (or MP4 container)
http://www.mede8erforum.com/index.php/topic,10.0.html

Handbrake v0.94 : http://sourceforge.net/projects/handbrake/files/0.9.4/

2. What have I been doing wrong? I need to work out what is causing the problem so I don't keep doing it. Is it because I have been using such old software? If so, I can't understand why as RipIt4ME, DVDShrink and DVD Decrypter seem to be well respected all over the place.
Media player like mede8er using strict rule for decoding, and those encoder seems only good for playing movie from PC which has more flexible rule
It also depend on which profile do you choose, some unmatching profile will not play on mede8er


3. What do you recommend I use in future to rip with so as to avoid this problem?
see point 1 Smiley

4. The Mede8er seems to be the only thing that struggles with my files. All the software players have no problems at all. Why is Mede8er so picky!?

not only mede8er if you say so, with different player (with same chipset) will suffer the same. they have the same SDK from realtek, and codec rules will apply for them
