Had used PVR 350's for analog cable turners in the past. However need to update to low profile or USB tuner card.
Looking of suggestions for a tuner that will receive analog cable, if it will also tune clear QAM channels that would even be better.
Normally I would recommend Hauppauge, but according to the wiki there is not a lot of support yet for the items that are currently available on-line (amazon, newegg, etc).
I would recommend picking-up an HVR-1250 or an HVR-2250 used. You could plug it in and get it working right away.
The wiki states the HVR-1250 does not have analog support, but I am running LinHes 8.3 and the required entries for the HVR-1250 are shown in /dev on my system. That said, I have not tried to record from them.
