Hi,

I'm working on a Schneider DVR HDD 80 that won't recognize the drives. It
boots up, I can search channels and access the menu. However, the DVD
doesn't get read, after a while it shows "def disc" on the screen. Drive
itself is ok, installed it on my computer and watched a DVD. HDD is also
fine. With a LG DVD burner installed instead of the internal drive it
sometimes starts to format the HDD, but will fail with "reset_mbr failed"
or "max_user_lbaffffffff failed" after some seconds. Resoldering the IDE
connectors didn?t solve the issue. As far as I understood the chipset
announcements and block schematics for that platform, there are two IDE
busses, the encoder has its own bus for controlling the HDD.

The unit is the same as Tevion DVD 160 HDD II (MD80857) despite
the smaller harddisk, MPEG board is LRM302710-0201, chipset is Cirrus
CS98301-CMZ/CS92689-CBZ. Cirrus (Magnumsemi) refused to give informations,
datasheets are only given to customers.

Any hints on this?

Thanks,
Sebastian
