Does anyone have one of these, or have any information about this player such as chipset or what limitations it has?

I posted a thread in the xvid forum asking for help about encoding xvid files for it (http://forum.doom9.org/showthread.php?t=114344) that I probably should have posted here instead.


So far what I've found is that it can play a surprising amount of "test clips" from the divx test cd 2.0. Among the clips it passed are:
B-Vops, 2 consecutive (skips on 3)
GMC, 1 warp point (skips on 3)
Packed bitstream
4500kbps bitrate stresstest (stutters on 6000)
Custom matrix, partial pass, slight blockiness in the first 3 seconds
All mp3/ac3 clips, including multi audios and vbr

I also made a 1500 frame testclip of Goldfinger, in the beginning with the flyby in miami beach up until Bond meets Felix at the pool. Here I was able to play a Q2 xvid encode with AS5 profile, b-vops, packed bitstream and almost 6000 average bitrate over the clip. However when I encoded the full movie in ~2000kpbs average rate with Home Theater proflile enabled, I get flickers in the bottom part of the frame at several occasions over that same sequence.


These results make no sense to me and I'm starting to think maybe it is some filesize problem (the full movie encode was 1993 mb, slightly undersized from my 2000mb targetsize, audio included). Do any other chips have limitations like that? My next test is going to be to remux it and split it in two 1gb files and see if that makes any difference.


I've searched for any info on this unit but haven't found anything. The only other sharp player I've found any info about was a standalone dvd with divx support and a ESS vibratto (sp?) chipset.

Could B-Vops have different "limitations" on framesize and such things than P-Vops in the player perhaps?

I ask because I encoded a 2.35:1 movie with my usual b-vops settings (2/1.62/0) and it plays fine, while my first 16:9 movie flickers with b-vops but seems to play fine if I disable them. The 16:9 move is encoded in 704x464 and the 2.35:1 is encoded in 704x368.

It also seems the problem with flickering in the lower part of the screen only appears if I also have ac3 sound, which is why it didn't show up in my no-sound Q2 test clips before! *doh*
