Hi all,
I am having some trouble with MPEG1 files that i haven't seen covered here yet, and am wondering if anyone can help.
I am trying to play a MPEG1 video file (with audio) in MoviePlayer 1.1 on my NX60 from a CF card using the EruWare/AthenaAmerica drivers. The Video is encoded using the following specifications:
MPEG1
160x160 resolution
30fps
300kbit
128kbit audio layer 1 @ 44100 Hz Mono.
As you can see, this is not a challenging file (which you can download if you'd like to try it on yours here: here (http://www.cowger.us/MOV00001.MPG) )
My problem is that every 2 seconds or so the video will pause for about 100ms, then keep playing at a reasonable framerate. During the stutter, the audio continues without a hitch. Some things I have tried:
* Dropping the frame rate to 15fps
* Dropping the encoding rate to 100kbit
* Dropping the sound down to 96kbit
* Playing the file on my computer from the CF card in case the card can't handle the read speed. It can.
* Killing any background apps
I would appreciate someone downloading the file and trying it on their NX series (they all have the same processor, right?) and seeing if it will play. Any other ideas as to whats wrong? If it the CF card? I dont have a memory stick to try this on at the moment.

I think I have it solved....it appears that movie player is EXTREMELY picky about resolutions and bit rates. The best compromise I could find in video that was smooth and looked good and sounded reasonable (output from TMPGEnc) was the following settings:
MPEG-1
Video: 304x224 12fps CBR 200kbps,
Audio: Layer-1 44100Hz 64kbps
This will get you 2hrs of video on a 265MB card. I'm leaving the above post here in case people search by keyword.
