>> From what I've read Comcast uses two levels of encryption, a basic one

>> comprehensive key encryption for their digital preferred channels.
>> I use a combination of two set top boxes, a PVR HD for HD channels and a
>> PVR500 for SD channels, and two Clear Qam adapters for locals.
>> The Clear Qam are very good quality MPEG 2 HD or SD streams with AC3
>> audio, the PVR500 is reasonable, but one my boxes has interference on the
>> svideo output.
>> The HD-PVR is really good, giving an H264 with AC-3 passthrough TS
>> stream. However, every now and then the cable box glitches and the HD-PVR
>> stops streaming. PVRInput isn't aware (yet - although Lars is looking
>> into it) that it's not sending anything to VDR. This is a problem when
>> recording as VDR restarts, if I'm doing concurrent recordings then I lose
>> bits of other recording during this time. As an aside, AC-3 is passed
>> through from the original ATSC-QAM stream, I had to patch VDR again to
>> stop checking for ATSC on Audio Type 0x81 or VDR would ignore the audio
>> dpid of the channel and set it to 0. This also had to be done for the
>> VNSI plugin in XBMC-PVR.
>> I really want to thank Lars for teaching me about TS streams..
New question - what hardware support is there for VDR and ATSC? I'm moving
to the US, so will be ditching my DVB-C and DVB-S hardware - what should I
be buying to work with VDR?
