mediamvp network interface with only 10 mpbs?

[Turas]

livetv on my media-mvp, using my digital twinhan dvb-c and cyberlink mux, always has problems. after some time (30s - 1m), the picture shortly shows some 'glitches' and afterwards video / audio get out of sync and playback begins to "stutter" and freeze.

i found out, that using the ms-mux reduces the problem. video / audio stay in sync when i use the ms-mux. but the short 'glitches' still occur, and sometimes the hauppauge remote (34-key) stops working at all. (i'm using mvpmc-emulation with latest vista-alpha-dongle atm).

looking at the network-traffic during playback of my server shows 6-8 Mbps with some 'spikes' over 10 Mbps... so here's my question:

- since my mediamvp (i'm using ethernet-mvp) is quite old: is it possible, that the mediamvp only has a 10 mbps interface? or has every mediamvp a 10/100 mbps interface?

All the models of the mvp the have the same 100 mbs NIC but the machine itself is only spec'd for MP@ML throughput which is max 15 mbs in the lab and most people can't get this for a variety of reasons, the NIC itself being one of them.

I can hit about 11 mbs CBR with mvpmc but from my observation a lot of people can't get 9 mbs out of their own networks so I think your results are normal. Keeping the demux full at that bit-rate is likely the cause of the issues and increase the pre-buffering a few 100ms might help a tiny bit.

thx for all the information!

my 'server'-system (cellar) is now equipped with an PCI Intel PRO/1000GT, 10/100/1000 MBit pci-express card. it's connected to the mvp (living room) via 3com 'Gigabit Switch 8'. using CAT 5e cabling (~15m). everything set to 'auto'.

since i use the pcie-card instead of the onboard lan, quality has got better. i think i could (and have to) live with the 'glitches'. the thing that hurts most is that the remote stops working. (and a bit, that i'm forced to use the ms-mux )

thx again and br

i dont have mvp or dvb-c
but i do have dvb-s and noticed the gliches reduced when i set the recording service priorty above normal in config

[Turas]

tried setting to above normal already. doesn't seem to help with my setup though.

[stustunz]

ok just thought it may have helped so when you watch from the pc the video is fine?

[Turas]

yes. watching directly is working fine for me.

Good and I hope you have set it back. I don't recommend changing the priority, in my opinion it's being misused at times, and can see where it actually hurts performance.

@ Turas have you tried other versions of the cyberlink mux?

[Turas]

i've set back priority.
and i've tried 3 different cyberlink muxes.
- 5.0.2022 (coming with twinhan app)
- 5.0.1307
- can't remember

still. the only mux that works acceptable in my system is the microsoft mux.
