I'd suggest a detailed information matrix with current and obsolete (EOL) product specifications to easily compare old and new products.

For instance showing

1) Techical component detail:

Pinnacle product (name and number)
- Digital Video Decoders (SAA7111A, SAA7114, SAA7113, SAF7113, SAA7115, SAA7115A, SAA7118, SAF7118, SAA7119, SAA7117A, SAA7144)

 component based specs (like www.nxp.com/acrobat_download/ literature/9397/75015904.pdf)

- etcetera

2) Functional specification 

- MPEG 2 / 4 / DivX with resolution and framerates/

- view incoming AV-data, with/without sound when creating DVD on HD or DVD.

- etcetera

3) Originally bundled software

4) Update options for bundled software

etcetera.

Just my 2c,

Eduard
