(Some cable boxes have FireWire outputs, but cable operators often encrypt the IEEE-1394 output for some of the channels tuned by these boxes.) Such a product is currently the only way to record HD content from providers that encrypt their digital data streams. At least one product, though, the Hauppauge HD PVR, encodes analog HD output, as produced by cable or satellite TV boxes. Most cards of this type are designed to encode standard definition analog (NTSC, PAL, or SECAM) video signals. You can transcode to MPEG-4 after recording to save space, if desired, but this requires post-record processing and will degrade quality slightly. The main drawback of this type of card is that you're limited to the video format and encoding options supported by the manufacturer (usually MPEG-2).

Most hardware-encoding cards output an MPEG-2 stream, which can simplify backing up to DVD.

The reduced load means that your video stream is less likely to suffer from encoding "hiccups" if a process causes the system to become momentarily too busy to process the video.This is particularly important for machines with weak CPUs or when using multiple tuners in one system. Greatly reduced load on the entire machine (with certain technical caveats).These cards, currently the Hauppauge PVR cards, the AVerMedia M179 and any other card which supports the V4L2 MPEG Encoder API, have a video processor on-board which compresses the tuned video signal into an RTjpeg, MPEG-2, or MPEG-4 program stream before sending it into the computer.

MPEG-4 is particularly demanding for systems with weaker CPUs, RTjpeg consumes less CPU time at the cost of larger file sizes and more digital video artifacts. Depending on your encoding settings, you may need close to 1GHz of CPU speed to handle a single encoding stream, and more if you have multiple cards or want to play back while recording. The main disadvantage of this type of card is the high CPU requirements.

If you have the CPU power, MPEG-4 produces better quality with smaller file sizes than the MPEG-2 used with most hardware encoding cards.

High flexibility - you can choose your encoding method and employ filters prior to encoding.

These cards deliver an unencrypted data stream to MythTV, which then encodes to MPEG-4 or RTjpeg using software encoders. Just be mindful that its interface is USB 2.0 - that may or may not be an issue depending on your system.These cards (also called frame grabbers and software encoders) are usually based on a chipset like the Bt848/878 or Conexant cx2388x, and decode broadcast NTSC, PAL, or Secam television.

Don’t be dissuaded by the name though, the 2 PLUS is a great capture card.

Continuous recording is possible when using "exFAT format" microSD cardĪvermedia ranks here with the most convoluted product name of all-time, the Live Gamer Portable 2 PLUS. When using the "FAT32 format" microSD card, due to the specification of FAT32, movies are divided and saved every 4 GB (about 25 minutes)

Micro SD Supported formats: FAT32 format / exFAT format.

Micro SD maximum capacity support: 128GB.

Micro SD Class 10 card is required for PC-Free recording, Micro SD card is not included.

LGP2 PLUS does not support viewing/recording/streaming of HDCP protected signals.

Record Format: MPEG 4 (H.264+AAC) / MJPEG / Supports hardware encoding.
