My HVR 1900 shows this:
[  430.837924] tveeprom 6-00a2: Hauppauge model 73219, rev D1E9, serial# 
5380960
[  430.837929] tveeprom 6-00a2: MAC address is 00:0d:fe:52:1b:60
[  430.837932] tveeprom 6-00a2: tuner model is Philips 18271_8295 (idx 149, 
type 54)

There is no problem with noisy video. But I still run a 2.6.32 kernel.


your box:
[   16.028218] tveeprom 3-00a2: Hauppauge model 73219, rev D1F5, serial# 
7116487
[   16.028228] tveeprom 3-00a2: MAC address is 00:0d:fe:6c:96:c7
[   16.028236] tveeprom 3-00a2: tuner model is NXP 18271C2 (idx 155, type 54)

The driver is for both tuners the same. I suspect that there is a hardware 
difference which would require to do some settings not only when using the dvb 
device, but also for the analogue mode.

You could also try an older kernel. There are currently a lot of 
regressions...
