Stuttering/Buffering video

[EFORCE]

Ping results:
Before Playback: bytes 32 Time <1 ms TTL 64 constantly
During playback: bytes 32 Time <1 ms TTL 64 constantly

I stopped the movie aftre about 5 minutes (since it was buffering from the beginning last time), cleared the movie cahce and played it again with the same result. Stopped and played a different movie (ISO DVD5), which did buffer quite a few times, but at the time the ping still showed the same result.

Could it be an issue with the decoding or the fact that it is an ISO (however I do not believe it is limited to ISO). I primarily play DVD rips (DVD 5 and 9), no DIVX.

I stopped the ping and then pinged the NAS, but get the same result, but with every now and then an =1 or = 2ms result, but at that time no buffering occurred.

There is one thing I changed to the NAS config today and that is that I stopped the SABnzb service that was running. Even though it didn't download anything it could use of some resources. I know the Synology CS407e is not the fastest NAs but this 4 bay baby should be capable of streaming just fine. Accessing the Video folder on the NAS while playing a move from a subdir of that folder didn't work

It's probably time for another debug log during playback.

Also do you have access to your NAS' logs by any chance? might be something useful in there.

And another thing, does your NAS allow for FTP connections? cause you can try setting up an FTP source in XBMC4Xbox, rather than SMB and see if that works any better.

Thanks Dan Dar,
Last DEBUG didn't really help as it only mentioned something about "waiting for data".
The NAS does support FTP, also WEBDAV, but i always thought FTP was not supposed to be used for streaming?
