Hello all. My mediagate mg35 is currently used as an external harddrive through usb2. I did buy it to play avi format films but all the latest films are too jerky to watch. It seems to me the latest codecs are too powerful for this machine. Am hoping someone might be able to rectify my little problem as l'd love to use the mediagate for its intended use.. Dont seem to read about others with the same problem. I am using the original firmware version 1.4.5 One other thing, l really dont know much about this sort of thing so any advice would need to be newby speak with step by step stuff. Sorry l know thats a pain as l am proficient in my area of expertise and have difficulty with people learning my craft.. With fingers crossed.. Tell.

The processor of this device is not good enough to play even 640x320 videos. I had it for a few weeks and returned it for a refund. I have now a Tvix M-4000P which has superb quality and an FTP server.

The processor of this device is not good enough to play even 640x320 videos. I beg your pardon but mine plays DVD quality videos (720X480 mpeg2) perfectly. It certainly ought to, since it has the guts of a DVD player including a big ASIC designed to do just that. It will even do a credible job of upconverting to HD. It will not, however, play HD video at all. So, if the OP was trying to play some HD mpeg4 files, that might explain his issue.

Thankyou THe Krell for your comments. Loaded a typical avi that l'd like to play without the jerky movement on my mg35 and Gspot came up with the following..
Video codec: Dx50/xvid Name: Divx 5.0.. bitrate 649kbps.. fps 23.97. Krell are you suggesting l should be able to play these avi's without jerky movement? Im not playing high definition,lm not sure if that is what you mean by HD. I am a newbie and struggle with the terminology. Appreciate any advice you can offer, as l see you have experience in the area.. Thanks again. Tell.

That looks like something which should play. Are you pulling it off the network or from the internal hard drive?

Mine plays most standalone AVIs or MPGs fine over the network, but jerks/stutters when playing higher bitrate DVD ISO. I copy those to the internal drive and it always works fine with that arrangement.

Video codec: Dx50/xvid Name: Divx 5.0.. bitrate 649kbps.. fps 23.97. Krell are you suggesting l should be able to play these avi's without jerky movement? Yes. I converted a bunch of mpeg2 program streams using DrDivX 2.0 and IIRC the DivX 6.4 codec because no official MG-35 firmware release will play AC3 audio in mpeg-2 program streams. I don't remember what data rate I selected, but I was trying for the least lossy copy I could get, which should mean the least compact data format and most likely to stress the MG-35. But it did not. All files played fine, including the AC3 sound tracks which were retained by DrDivX.

Incidentally, the MG-35 firmware plays AC3 audio just fine in mpeg-4 program streams (such as the DivX files I made), as well as within ISO files of ripped DVDs, or IFO/VOB files. I think all those that I made were done on 30fps videos, not 24fps as yours are. Hmmm.

Oh yes. And HD = High Definition. Of course you can get an argument over exactly what constitutes HD, but in general it's something with higher resolution than a standard DVD, nowadays called ED = Extended Definition. :rolleyes:

Yes Bytre, these avi files lm playing from the mg35's harddrive onto the telly. The older avi's work fine but the newer ones have jerky movement to an unacceptable level. The audio is fine. I dont have any trouble playing them on the computer... Thank you Krell for your input. I have a feeling the problem is a salient one but my description of equipment or software is inadequate. ive just placed another avi into gspot, this time l will share a little more of its spec's as follows,
codec xvid name xvid, runtime 01.08:49(103,225 xy 640x272
bitrate 1215kbps fps 25 qf 1.279bit/pixels.
audio name ac3(0x2000 dolby, codec 194kbps (96/ch,stereo cb
file size 695mb. Krell if you can think of something l can try l'd look forward to it.Again l really dont know anything about video lingo so would appreciate any advice you can offer in childrens terms.. thank again . Tell.

I've had no problem playing most MPEG-4 videos (Divx/Xvid) on the MG-35 with resolutions up to DVD quality (740x480).

However, I have found that its playback engine is less fault tolerant than some other content streamers, like Tvix.

It plays back all of the DVDs I personally ripped with Auto GK, as 640px width Xvid video (and an AC3 audio).

It plays about 90-95% of the videos I've downloaded. A couple of videos that play on the Tvix will not work on the MG-35. Neither support video encodes using GMC or QPEL.

I use the MG-35 purely for streaming video over ethernet. No hard drive installed.

I reckon that you will change your mind if you try an EM8621 based box.
Perhaps this isn't noticeable on small screens, but the MG-35 plays low resolution avi showing pixelated images on a 40" for example (blocky areas), most visible on dark scenes.

There is a huge difference with a Tvix 4000 (EM8621 based), for example, that plays the same avi with such a smooth rendering that almost it does not look like the movie is low resolution.

Interesting comment; I have noticed this too on low resolution DivX videos made from mpeg-2 originals. This effect is completely absent on the full resolution mpeg2 originals. So my statement about 720X480 resolution DVD videos still stands. But I will take your word for it that the Tvix does a better job of upscaling, which could perhaps help out the OP if he's willing to pay Dvico's prices. I am contemplating this move myself, in order to get fairly-well-debugged firmware. Al Tech is not know for their bug fixes. :(

thanks Austinv for your comments, Do you ever get the jerky movement on some avi's ? Heydude, l might invest in and tvix 4000 , will look into it thanks man. Im really surprised no one else has seen this problem, it happens with virutally every avi i pull off the web.
