Hi, Steve,

I tested analog tv as well as composite/s-video input, it is working
properly. I still cannot manage to get digital tv working, even after
getting proper values of the registers from regspy. I get a ton of 
ts_oflow interrupt as soon as I use azap to tune to any digital channel.
I couldn't figure out what the problem is, but I am sending this
following patch anyway so that other people can test/debug. As I
mentioned, the register values are the ones reported by regspy in
windows while digital tv was working, so I believe these to be correct.

Can you apply this to your tree? Thanks!

Anyone familar with cx88 risc/dma operations, if you see anything I am
doing wrong, please let me know.

PS: I am cc'ing this to the linux-dvb list.
