after installing latest openwrt [12.09, 25 apr] on my dir-825, i found that the windows network scanner isn't discovering any device. i used latest drivers for both devices, router and pc.
the router is identified as openwrtmipsr3. after installation / restart i must run manually /opt/bin/mediaclient --start. then, after enabling network in driver, i can see the device locally:
root@home:/# /opt/bin/mediaclient  --scan-network

i can access port 9234 via telnet, from windows [7, 64 bit] - but that's all.
---later edit---
without any modification, the device is now shown in windows network scanner. but now dvbviewer (default settings and codecs + your recommendation), will only scan channels; selecting any of them will give 0% signal. if i'm setting manually the device, eq
mediaclient -m DVBC -f 306000000 -S 6900000 -M Q64i'm able to use channels on that transponder.
progdvb will function correct.
