I do not know what just happen like 5 days ago one of my Europen Music Chanel links stop working.
I did not update the zip or make any modification on my server. All other channels i have are working good.

Can I ask someone the test this link it play on local browser and it played on ROku for last 6 months as the other songs.

here is the sample link : http://telestream.interia.pl/teledyski/HQ/q/s/Ania_Wyszkoni0_Ania_25550.ehfjw

All i got is : " Request Failed: -3: An unexpected problem (but not server timeout or HTTP error) has been detected."

Looks like some new firmware overnight update again broke my channel.

What kind of file is this?

Roku firmware for the original series was updated at the end of last year, as was firmware for the Roku2. Perhaps the company where you host your servers made some changes to their network, or automatic software updates ran on your server, lots of things that can happen.

There's nothing wrong with the file. I can download it and play it. When I try to play it directly from the link on my XD|S, I get "play failed: Network error. This could be caused by any of the following problems: (1) The server is down or unresponsive. (2) The server is unreachable. (3) There is a network setup issue on the client." Worse, when I try it on my Roku 2 XS, the box crashes and reboots.

The stream plays fine using VLC Media Player, but when I try to play it on my Roku 1 (version 3.1/1011), I get the following error:

Network error.  This could be caused by any of the following problems: (1) The server is down or unresponsive. (2) The server is unreachable. (3) There is a network setup issue on the client.

Here's the output from mediainfo (I had to change the filename extension from ehfjw to mp4 for mediainfo to work):

I wonder if the Roku doesn't like the weird filename extension.

Check against the encoding guide in the SDK. 25FPS isn't supported.

[shantyman]

"Check against the encoding guide in the SDK. 25FPS isn't supported." Patrick all EU videos are encoded in 25FPS rate we have PAL system not NTSC like 29FPS this is not a issue with the frames,
same videos worked on Roku for over 6 months and we had no problem with the links or extensions it just stop working few days back.
if is not Roku engines updates it must be us.
I just need this to get fixed and looking for solution.

This might be a longshot, but I had that error before when I had by accident a .mp4 file that was not an xml file in my xml directory on my server and it gives that error. Removed the file and all was good. Plus, can't trust Handbrake for fps. I had a video at 29.97 and still reported 25 on many videos.

[unDEFER]

Here yet another link from the same server. And this links also plays with the latest roku firmware:
http://telestream.interia.pl/teledyski/HQ/n/9/Kawa5_KawaLato_Pali_25265.yfcz9
It has also 25 fps. So why other links broken???

There is a problem in the ctts tables in those encodings.

This is what a normal ctts looks like:

00 00 00 01 00 00 03 e9 00 00 00 01 00 00 0b bb 
00 00 00 02 00 00 00 00 00 00 00 01 00 00 0b bb 
00 00 00 02 00 00 00 00 00 00 00 01 00 00 0b bb 
00 00 00 02 00 00 00 00 00 00 00 01 00 00 0b bb 
etc.

Each entry is two 4-byte words, the first is a count and the second a time offset. Note the count values in this example are 1, 1, 2, 1, 2, etc ...

This is what the ctts looks like in the first URL you posted:

00 02 00 00 00 01 00 00 00 03 00 00 00 01 00 00 
00 01 00 00 00 01 00 00 00 03 00 00 00 01 00 00 
00 01 00 00 00 0e 00 00 00 02 00 00 00 01 00 00 
00 03 00 00 00 01 00 00 00 01 00 00 00 0a 00 00 
etc

This doesn't make sense when interpreted as 4 byte integers. It seems to be using 2-byte (16 bit) values. I have not found any reference to 16 bit values being allowed in this atom, but perhaps there's some extension that I'm not aware of. In any case, the Roku player does not support this and expects ctts to hold 32-bit values.

wow, I have no idea what this means , but again we had the all links working fine till 5 days ago
and there is no way they re-encode 1.5TB of data just to make CTTS table errors , and they did not change any way they encode
