As an encoder you could try a philips TDA2001 or Motorola MC1377. These work OK for games but are not professional encoders I'm affraid the only way to get decent encoded video, is to do it with separate modulators etc. --------------------------------------------------------------------- email to UUCP: uunet!mimsy!{arinc,fe203}!vk2bea!michael _ _ _ _ Amateur | VK2BEA (Australia) ' ) ) ) / // Radio | G4NYV (United Kingdom) / / / o _. /_ __. _ // Stations| NV3Z (United States) / ' (_<_(__/ /_(_/|_
