LSI chipset onboard Toshiba combo variants?
 

The Toshiba DVD/VCR combo deck model D-VR4 is listed with this site as having an LSI filtering chipset on board:

Would anyone know if a similar model, D-VR4XSU uses this chipset, as well?

That list was copied from the LSI Logic site. However, I'm pretty certain no Toshiba has ever used an LSI Logic chipset.
That may be a listing that was published before the model was created.

This was an unanswered question or unresolved issue found during a site audit. It's hard to have an FAQ when the answers are missing, or final outcomes are unknown. At The Digital FAQ support forum, questions are never intentionally ignored, and may have been missed due to a forum glitch or human error. More details on the audit.
