Just to add another note

Just to add another note which is probalby a deal breaker to most consumers. With Tivo you don't get access to any of the On Demand or PPV stuff. No high def CSI, Sopranos for you!

The Comcast PVRs are

I think your article overlooked the easiest way to record and watch cable. Use the cable companies stuff.

The Comcast PVRs are integrated with their programming. And they have recently upgraded the software. With the Comcast hdtv pvr ($15/mo), you get *three* high-def tuners. That's right.

With Tivo, you have to buy the box for $300, and pay monthly fees for the guide, and monthly fees to the cable provider for the cards. And arguably you still have an inferior product to the comcast pvr.

Missing Premium Channel on Tivo

The issue with your missing premium channels probably has to do a mismatch with the sub-streams of the MPEG transport.

For example, make sure there is only one video stream and that its PID is matches the PCR PID, that is if the provider embeds the PCR (program clock reference) in with the video stream. Make sure that the video stream is a type 0x02 (ISO-138181). The other types of video are MPEG-1 - (will not work) and SCTE (another MPEG-2 video standard). I believe the TiVo can decode SCTE (0x80), but have not verified.

Another common problem with the cablecards is no audio on a few channels. This may be attributed to the TiVo 3 or cablecard-ready television's inability to decode the audio type. Unfortunately, the audio codecs used is not always consistent with the content providers. In regards to the TiVo 3, The last I checked (within past 6 months), it cannot decode MPEG-2 audio. Typically, cable companies use AC3 (Dolby Digital) to deliver audio, which is what is defined by the ATSC and used by TiVo and many televisions. Hence, why TiVo does not play audio when audio is MPEG-2 audio. Check with the cablecard-ready television or TiVo manufacturers for a firmware update to add the codecs.

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
