Item 1.Security and Issuer This Amendment No. 13 to Schedule 13D on Cablevision Systems Corporation (the "Issuer") is being filed on behalf of the undersigned to amend the Schedule 13D, as amended (the "Schedule 13D") which was originally filed on December 11, 1995. Unless otherwise indicated, all capitalized terms used herein but not defined herein shall have the same meaning as set forth the Schedule 13D. Item 2. Identity and Background This statement is being filed by Mario J. Gabelli ("Mr. Gabelli") and various entities which he directly or indirectly controls or for which he acts as chief investment officer. These entities, except for Lynch Corporation ("Lynch"), Spinnaker Industries, Incorporated ("Spinnaker"), Western New Mexico Telephone Company ("Western New Mexico"), Entoleter, Inc. ("Entoleter"), Lynch Telecommunications Corporation ("Lynch Telecom"), Lynch Telephone Corporation ("Lynch Telephone") and Inter-Community Telephone Company ("Inter-Community") (collectively, "Lynch and its affiliates"), engage in various aspects of the securities business, primarily as investment adviser to various institutional and individual clients, includ- ing registered investment companies and pension plans, as broker/dealer and as general partner of various private invest- ment partnerships. Certain of these entities may also make investments for their own accounts. The foregoing persons in the aggregate often own beneficially more than 5% of a class of equity securities of a particular issuer. Although several of the foregoing persons are treated as institutional investors for purposes of reporting their beneficial ownership on the short-form Schedule 13G, the holdings of those who do not qualify as institutional investors may exceed the 1% threshold presented for filing on Schedule 13D or implementation of their investment philosophy may from time to time require action which could be viewed as not completely passive. In order to avoid any question as to whether their beneficial ownership is being reported on the proper form and in order to provide greater investment flexibility and administra- tive uniformity, these persons have decided to file their benefi- cial ownership reports on the more detailed Schedule 13D form rather than on the short-form Schedule 13G and thereby to provide more expansive disclosure than may be necessary.

(d) and (e) - On December 8, 1994, the SEC instituted and simultaneously accepted offers for the settlement of an administrative proceeding against Gabelli & Company and GAMCO. The order instituting the proceeding included a finding, which Gabelli & Company and GAMCO neither admitted nor denied, that they failed to implement and maintain policies and procedures reasonably designed to prevent the misuse of material, nonpublic information by not sepecifically addressing the special circumstances that arose from their affiliation with Lynch Corporation, a public company. To resolve this matter, Gabelli & Company and GAMCO agreed to cease and desist from violating Section 15(f) of the 1934 Act and Section 204A of the Advisers Act, respectively. They further agreed to each pay a civil penalty in the amount of $50,000, and to retain, and adopt the recommendations of, an independant consultant regarding their Section 15(f) and Section 204A policies and procedures. On December 13, 1991, the Virginia State Corporation Commission entered an order of settlement in final disposition of matters arising from an allegation that GAMCO had transacted business in Virginia as an investment adviser without having been registered as such under Virginia Code Section 13.1-504A or an exemption therefrom. GAMCO consented to the entry of the order without admitting or denying the allegation and without a hearing. The terms of the order provide that GAMCO would pay a fine and costs totalling fifty-five thousand dollars and would not transact business in Virginia as an investment adviser unless it was registered as such under section 13.1-504A or was exempt from registration. (f) - Reference is made to Schedule I hereto. Item 3. Source and Amount of Funds or Other Consideration All Reporting Persons used an aggregate of approximate- ly $5,338,734 to purchase the additional Securities requiring this Amendment to Schedule 13D. GAMCO and GFI used approximately $4,150,334 and $1,188,400, respectively, of funds that were provided through the accounts of certain of their investment advisory clients (and, in the case of some of such accounts at GAMCO, may be through borrowings from client margin accounts) in order to purchase the Securities for such clients. Item 5.
